DTC143TCA Datasheet - Rectron Semiconductor

FEATURES
* Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors.(see equivalent circuit).
* Only the on/off conditions need to be set for operation marking device design easy.
* 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.
