These devices consist of four independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible, as long as the difference between the two supplies is 2 V to 36 V, and V_CC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.

Wide Supply Ranges
- Single Supply: 2 V to 36 V
  (Tested to 30 V for Non-V Devices and
  32 V for V-Suffix Devices)
- Dual Supplies: ±1 V to ±18 V
  (Tested to ±15 V for Non-V Devices and
  ±16 V for V-Suffix Devices)
Low Supply-Current Drain Independent of Supply Voltage: 0.8 mA (Typ)
Low Input Bias Current: 25 nA (Typ)
Low Input Offset Current: 5 nA (Typ)
Low Input Offset Voltage: 2 mV (Typ)
Common-Mode Input Voltage Range Includes Ground
Differential Input Voltage Range Equal to Maximum-Rated Supply Voltage: ±36 V
Low Output Saturation Voltage
Output Compatible With TTL, MOS, and CMOS
