Feature Description (continued)

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 LMx11 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.
