DIGITAL TRANSISTOR (NPN)
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 device design easy.
