| UTC LM339 LINEAR INTEGRATED CIRCUIT QUAD DIFFERENTIAL COMPARATOR DESCRIPTION The UTC LM339 consists of four independent voltage comparators, designed specifically to operate from a single power supply over a wide voltage range. SOP-14 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.
