3 Description

The LM139A-MIL device consists 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 VCC 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.

The LM139A-MIL device is characterized for

operation over the full military temperature range of

–55°C to +125°C.
