UTC339 LINEAR INTEGRATED CIRCUIT

QUAD DIFFERENTIAL COMPARATOR

DESCRIPTION The UTC339 consists of four 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) *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 DIP-14 *Output compatible with TTL ,DTL, and CMOS logic system
