1 ? fn6469.1 isl54048, isl54049 ultra low on-resistance, +1.65v to +4.5v, single supply, dual spst analog switch the intersil isl54048 and isl54049 devices are low on-resistance, low voltage, bidirectional, dual single- pole/single-throw (spst) analog switches designed to operate from a single +1.65v to +4.5v supply. targeted applications include battery powered equipment that benefit from low r on (0.29 ) and fast switching speeds (t on = 40ns, toff = 20ns). the digital logic input is 1.8v logic-compatible when using a single +3v supply. cell phones, for example, often face asic functionality limitations. the number of analog input or gpio pins may be limited and digital geometries are not well suited to analog switch performance. this part may be used to ?mux-in? additional functionality while reducing asic design risk. the isl54048 and isl54049 are offered in a small form factor package, alleviating board space limitations. the isl54048 has two normally open (no) spst switches and the isl54049 has two normally closed (nc) spst switches. features ? on-resistance (r on ) - v+ = +4.3v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.29 - v+ = +3.0v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.33 - v+ = +1.8v . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.55 ?r on matching between channels . . . . . . . . . . . . . . . . . 0.06 ?r on flatness across signal range . . . . . . . . . . . . . . . . 0.03 ? single supply operation . . . . . . . . . . . . . . . +1.65v to +4.5v ? low power consumption (p d ). . . . . . . . . . . . . . . <0.45 w ? fast switching action (v+ = +4.3v) -t on . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40ns -t off . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 20ns ? esd hbm rating . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .>8kv ? 1.8v logic compatible (+3v supply) ? low icc current when vinh is not at the v+ rail ? available in 10 ld 1.8mmx1.4mmx0.5mm tqfn ? pb-free plus anneal available (rohs compliant) applications ? battery powered, handheld, and portable equipment - cellular/mobile phones - pagers - laptops, notebooks, palmtops ? portable test and measurement ? medical equipment ? audio and video switching related literature ? technical brief tb363 ?guidelines for handling and processing moisture sensitive surface mount devices (smds)? ? application note an557 ?recommended test procedures for analog switches? table 1. features at a glance isl54048, isl54049 number of switches 2 sw spst 4.3v r on 0.29 4.3v t on /t off 40ns/20ns 3v r on 0.33 3v t on /t off 50ns/27ns 1.8v r on 0.55 1.8v t on /t off 70ns/54ns package 10 ld 1.8mmx1.4mmx0.5mm tqfn ordering information part number (note) part marking temp. range (c) package (pb-free) pkg. dwg. # isl54048iruz-t b -40 to +85 10 ld 1.8x1.4x0.5 tqfn (0.40mm pitch) tape and reel l10.1.8x1.4a isl54049iruz-t c -40 to +85 10 ld 1.8x1.4x0.5 tqfn (0.40mm pitch) tape and reel l10.1.8x1.4a note: intersil pb-free plus anneal products employ special pb-free material sets ; molding compounds/die attach materials and 100 % matte tin plate termination finish, which are rohs compliant and compatible wi th both snpb and pb-free soldering operations. intersil pb-free p roducts are msl classified at pb-free peak reflow temperatures that meet or exceed the pb-free requirements of ipc/jedec j std-020. data sheet june 11, 2007 caution: these devices are sensitive to electrosta tic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-468-3774 | intersil (and design) is a registered trademark of intersil americas inc. copyright intersil americas inc. 2007. all rights reserved all other trademarks mentioned are the property of their respective owners.

precise switching capability from a single 1.65v to 4.5v supply with low on-resistance (0.29 ) and high speed operation (t on = 40ns, t off = 20ns). the devices are especially well suited for portable battery powered equipment due to their low operating supply voltage (1.65v), low power consumption (4.5w max), low leakage currents (195na max) and the tiny tqfn package. the ultra low on-resistance and r on flatness provide very low insertion loss and distortion to applications that require signal reproduction. external v+ series resistor for improved esd and latch-up immunity, intersil recommends adding a 100 resistor in series with the v+ power supply pin of the ic (see figure 7). during an overvoltage transient event, such as occurs during system level iec 61000 esd test ing, substrate currents can be generated in the ic that can trigger parasitic scr structures to turn on, creating a low impedance path from the v+ power supply to ground. this will result in a significant amount of current flow in the ic which can potentially create a latch-up state or permanently damage the ic. the external v+ resistor limits the current during this over-stress situation and has been found to prevent latch-up or destructive damage for many overvoltage transient events. under normal operation the sub-microamp i dd current of the ic produces an insignificant voltage drop across the 100 series resistor resulting in no impact to switch operation or performance. supply sequencing and overvoltage protection with any cmos device, proper power supply sequencing is required to protect the device from excessive input currents which might permanently damage the ic. all i/o pins contain esd protection diodes from the pin to v+ and to gnd (see figure 8). to prevent forward biasing these diodes, v+ must be applied before any input signals, and the input signal voltages must remain between v+ and gnd. if these conditions cannot be guaranteed, then precautions must be implemented to prohib it the current and voltage at the logic pin and signal pins from exceeding the maximum ratings of the switch. the following two methods can be used to provided additional protection to limit the current in the event that the voltage at a signal pin or logic pin goes below ground or above the v+ rail. logic inputs can be protected by adding a 1k resistor in series with the logic input (see figure 8). the resistor limits the input current below the threshold that produces figure 5. crosstalk test circuit figure 6. capacitance test circuit test circuits and waveforms (continued) 0v or v+

signal path inputs. adding a series resistor to the switch input defeats the purpose of using a low r on switch. connecting schottky diodes to the signal pins (as shown in figure 8) will shunt the fault current to the supply or to ground thereby protecting the switch. these schottky diodes mu st be sized to handle the expected fault current. power-supply considerations the isl54048 and isl54049 construction is typical of most single supply cmos analog switches, in that they have two supply pins: v+ and gnd. v+ and gnd drive the internal cmos switches and set their analog voltage limits. unlike switches with a 4v maximum supply voltage, the isl54048 and isl54049 5.5v maximum supply voltage provides plenty of room for the 10% tolerance of 4.3v supplies, as well as room for overshoot and noise spikes. the minimum recommended supply voltage is 1.65v. it is important to note that the input signal range, switching times, and on-resistance degrade at lower supply voltages. refer to ?electrical specifications? on page 3 and the typical performance curves on page 9 for details. v+ and gnd also power the internal logic and level shiftiers. the level shiftiers convert the input logic levels to switched v+ and gnd signals to drive the analog switch gate terminals. this family of switches c annot be operated with bipolar supplies because the input switching point becomes negative in this configuration. logic-level thresholds this switch family are 1.8v l ogic compatible (0.5v and 1.4v) over a supply range of 2.7v to 4.5v (see figure 18). at 2.7v, the v il level is about 0.53v. this is still above the 1.8v logic guaranteed low output maximum level of 0.5v, but noise margin is reduced. the digital input stages draw supply current whenever the digital input voltage is not at one of the supply rails. driving the digital input signals from gnd to v+ with a fast transition time minimizes power dissipation. the isl54048 and isl54049 have been designed to minimize the supply current whenever the digital input voltage is not driven to the supply rails (0v to v+). for example, driving the device with 2.85v logic (0v to 2.85v) while operating with a 4.2v supply the device draws only 12 a of current (see figure 16 for v in = 2.85v). frequency performance in 50 systems, the isl54048 and isl54049 have a -3db bandwidth of 120mhz (see figure 21). the frequency response is very consistent over a wide v+ range, and for varying analog signal levels. an off switch acts like a capacitor and passes higher frequencies with less attenuation, resulting in signal feedthrough from a switch?s input to its output. off isolation is the resistance to this feedthrough, while crosstalk indicates the amount of feedthrough from one switch to another. figure 22 details the high off isolation and crosstalk rejection provided by this part. at 100khz, off isolation is about 62db in 50 systems, decreasing approx imately 20db per decade as frequency increases. higher load impedances decrease off isolation and crosstalk rejection due to the voltage divider action of the switch off impedance and the load impedance. leakage considerations reverse esd protection diodes are internally connected between each analog-signal pin and both v+ and gnd. one of these diodes conducts if any analog signal exceeds v+ or gnd. virtually all the analog leakage current comes from the esd diodes to v+ or gnd. although the esd diodes on a given signal pin are identical and therefore fairly well balanced, they are reverse biased differently. each is biased by either v+ or gnd and the analog signal. this means their leakages will vary as the signal varies. the difference in the two diode leakages to the v+ and gnd pins constitutes the analog- signal-path leakage current. all analog leakage current flows between each pin and one of the supply terminals, not to the other switch terminal. this is why both sides of a given switch can show leakage curren ts of the same or opposite polarity. there is no connection between the analog signal paths and v+ or gnd. figure 8. overvoltage protection gnd v com v nx v+ in x optional protection resistor optional
