NPN EPITAXIAL SILICON TRANSISTOR

NPN DIGITAL TRANSISTOR

(BUILT-IN RESISTORS)

FEATURES

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

circuit without connecting external input

resistors (see the equivalent circuit).

*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.

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

making device design easy.
