DIGITAL TRANSISTORS

(BUILT- IN RESISTORS)

FEATURES

* Built-in bias resistors enable the configuration of an inverter circuit

without connecting external input resistors (see equivalent

circuit).

* 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.

* Only the on / off conditions need to be set for operation, making

device design easy.
