DUAL DIFFERENTIAL
COMPARATOR
DESCRIPTION
The UTC 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 ~ ±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.
