!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 positive 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 device design easy.
