UTC339 (Quad Differential Comparator IC)

Description

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 Output compatible with TTL ,DTL, and CMOS logic system Absolute Maximum Ratings(Ta=25°C ) Characteristic Symbol Value Unit Supply Voltage Vcc ±18 OR 36 V Differential input voltage VIDiff) 36 V Input Voltage VI -0.3~36V V Power Dissipation Pd 570 mW Operating Temperature Topr 0 to +70 °C Storage Temperature Tstg -65 to 150 °C Electrical Characteristics (Vcc=5.0V, Ta=25?,All voltage referenced to GND unless otherwise specified) Characteristic Symbol Test Condition Min Typ.
