DESCRIPTION/ORDERING INFORMATION

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 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 LM139 and LM139A are characterized for operation over the full military temperature range of –55°C to

125°C.
