8.3 Feature Description

for external offset adjustment or trimming.

The input stage is followed by a very high gain stage for very fast response after a voltage difference on the input

pins have been sensed.

This is then followed by the output stage that consists of an open collector NPN (pulldown or low-side) transistor.

8.4 Device Functional Modes

8.4.1 Voltage Comparison

The LM311-MIL operates solely as a voltage comparator, comparing the differential voltage between the positive

and negative pins and outputting a logic low or high impedance (logic high with pullup) based on the input

differential polarity.
