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.
