DESCRIPTION
The Contek LM393 consists of two independent voltage comparators, designed specifically to operate from a single power supply over a wide voltage range.

FEATURES
* Single or dual supply operation.
* Wide operating supply range (Vcc=2V~36V or +- 1 to +- 18V).
* Input common-mode voltage includes ground.
* Low supply current drain ICC=0.8mA(Typical).
* Low input bias current Ibias=25nA(Typical).
* Output compatible with TTL, DTL, and CMOS logic system.
