description

This device consists of a single voltage comparator that is designed to operate from a single power supply over

a wide range of voltages. Operation from dual supplies also is possible if the difference between the two supplies

is 2 V to 36 V and V is at least 1.5 V more positive than the input common-mode voltage. Current drain is

CC

independent of the supply voltage. The output can be connected to other open-collector outputs to achieve

wired-AND relationships.

The TL331I is characterized for operation from –40C to 85C.
