Features

!

1) Built-in circuit enables 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.
