This device consists of four independent precision voltage comparators, which are designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.


These comparators also have a unique characteristic in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.

Key features
  • Wide single supply voltage range or dual supplies for all devices: +2 V to +36 V or ±1 V to ±18 V
  • Very low supply current (1.1 mA) independent of supply voltage (1.4 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
