CONTEK LM339 Datasheet
LM339 LINEAR INTEGRATED CIRCUIT
QUAD DIFFERENTIAL
COMPARATOR
DESCRIPTION
The Contek LM339 consists of four independent
voltage comparators, designed specifically to operate
from a single power supply over a wide voltage range.
FEATURES
*Signal or dual supply operation.
*Wide operating supply range(Vcc=2V~36V).
*Input common-mode voltage includes ground.
*Low supply current drain ICC=0.8mA(Typical).
*Open collector outputs for wired and connection.
*Low input bias current Ibias=25nA(Typical).
*Low output saturation voltage.
*Output compatible with TTL, DTL, and CMOS logic
system.
