DIGITAL TRANSISTOR (NPN)
·Equivalent Circuit
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
