Product overview

Description

This device consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. The input common-mode voltage range includes negative rail even though operated from a single power supply voltage.
All pins are protected against electrostatic discharge up to 2 kV. Consequently, the input voltages must not exceed the VCC+ or VCC- magnitudes.
  • All features

    • Wide, single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V
    • Very low supply current (0.4 mA) independent of supply voltage (1 mW/comparator at +5 V)
    • Low input bias current: 25 nA typ.
    • Low input offset current: ±5 nA typ.
    • Input common-mode voltage range includes negative rail
    • Low output saturation voltage:250 mV typ. (IO= 4 mA)
    • Differential input voltage range equal to the supply voltage
    • TTL, DTL, ECL, MOS, CMOS compatible outputs
    • ESD internal protection: 2 kV
