Applications

Inverter, Interface, Driver

Features

1) Built-in bias resistors enable the configuration of an

inverter circuit without connecting external input

resistors (see equivalent circuit).

2) The bias resistors consist of thin film resistors with

complete isolation to allow negative biasing

of the input. They also have the advantage of almost

completely eliminating parasitic effects.

3) Only the on / off conditions need to be set for

operation, making the device design easy.
