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.
