NPN DIGITAL TRANSISTOR (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.
