1. general description the 74lv4051 is an 8-channel analog multiplexer/demultiplexer with three digital select inputs (s0 to s2), an active-low enable input (e ), eight independent inputs/outputs (y0 to y7) and a common input/output (z). it is a lo w-voltage si-gate cmos device that is pin and function compatible with 74hc4051 and 74hct4051. with e low, one of the eight switches is selected (low impedanc e on-state) by s0 to s2. with e high, all switches are in the high-impedance off-state, independent of s0 to s2. v cc and gnd are the supply voltage pins for the digital control inputs (s0 to s2, and e ). the v cc to gnd ranges are 1.0 v to 6.0 v. the analog inputs/outputs (y0 to y7, and z) can swing between v cc as a positive limit and v ee as a negative limit. v cc ? v ee may not exceed 6.0 v. for operation as a digital multiplexer/demultiplexer, v ee is connected to gnd (typically ground). 2. features and benefits ? optimized for low-voltage applications: 1.0 v to 6.0 v ? accepts ttl input levels between v cc = 2.7 v and v cc = 3.6 v ? low on resistance: ? 145 ? (typical) at v cc ? v ee = 2.0 v ? 80 ? (typical) at v cc ? v ee = 3.0 v ? 60 ? (typical) at v cc ? v ee = 4.5 v ? logic level translation: ? to enable 3 v logic to communicate with ? 3 v analog signals ? typical ?break before make? built in ? esd protection: ? hbm jesd22-a114e exceeds 2000 v ? mm jesd22-a115-a exceeds 200 v ? multiple package options ? specified from ? 40 ? cto+85 ? c and from ? 40 ? cto+125 ? c 74lv4051 8-channel analog multiplexer/demultiplexer rev. 5 ? 17 september 2014 product data sheet
