The push-pull CMOS output stage allows power and space saving by eliminating the external pull-up resistor required by usual open-collector output comparators. Thus response times remain similar to the LM393.

Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. The magnitude of the input and the output voltages must never exceed the magnitude of the positive supply voltage. Short circuit from outputs to VCC+ can cause excessive heating and eventual destruction.
