UTC LM393
LINEAR INTEGRATED CIRCUIT
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.
SOP-8
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.
