Wide Range of Supply Voltage

single power supply over a wide range of voltages.

–

Maximum Rating: 2 V to 36 V

Operation from dual supplies also is possible as long

as the difference between the two supplies is 2 V to

independent of the supply voltage. The outputs can

Voltage: 0.4 mA (Typical) Per Comparator

be connected to other open-collector outputs to

achieve wired-AND relationships.

•

Low Input Bias Current: 25 nA (Typical)
