Description
Characteristics
Pin Assignment
The Universal Standard family LM393/
LM339/LM2903/LM2901 monolithic ICs
integrate two/four independent
comparators on a single chip and feature
high gain, low power consumption, and
an operating voltage range from 2[V] to
36[V] (single power supply).
1) Operating temperature range
2)Open collector output
3)Single / dual power supply compatible
4)Low supply current
