The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC + -1.5V, but either or both inputs can go to +30V without damage. Positive voltage excursions of one input may exceed the power supply level. As long as the other input voltage remains within the common-mode range, the comparator will provide an appropriate output state. The low input voltage state must not be less than -0.3V (or 0.3V below the negative power supply, if used). The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals, 300ns can be obtained 3/7 TSM109/A COMPARATOR (comparator with inverting input connected to the internal Vref)) VCC+ = +5V, VCC-= GND, Tamb = +25C (unless otherwise specified) TSM109 Symbol Input Offset Voltage - note 1) Tamb = +25C Tmin Tamb Tmax Input Bias Current for positive input note 2) Tamb = +25C Tmin Tamb Tmax Large Signal Voltage Gain VCC = 15V, RL = 15k, Vo = 1V to 11V Low Level Output Voltage Vid = -1V, Isink = 4mA Tamb = +25C Tmin Tamb Tmax High Level Output Current (Vid = 1V) IOH VCC = Vo = 30V Tamb = +25C Tmin Tamb Tmax Output Sink Currrent Vid= 1V, Vo = 1.5V Response Time - note RL= 5.1k connected to VCC+ Large Signal Response Time RL= 5.1k connected to VCC+, el = TTL, V(ref) = +1.4v + Parameter Min.
