QUAD DIFFERENTIAL
COMPARATOR
SOP-14
LINEAR INTEGRATED CIRCUIT
DESCRIPTION
The UTC
LM339
consists of four independent voltage
comparators, designed specifically to operate from a single
power supply over a wide voltage range.
TSSOP-14
FEATURES
*Signal or dual supply operation.
*Wide operating supply range (Vcc=2V~36V).
*Input common-mode voltage includes ground.
*Low supply current drain I
F
=0.8mA (Typical).
*Open collector outputs for wired and connection.
*Low input bias current I
BIAS
=25nA (Typical).
*Low output saturation voltage.
*Output compatible with TTL, DTL, and CMOS logic system.
