QW-R104-002,B
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 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.
