DTC144TCA Datasheet - Weitron Technology

Features:
* Built-in bias resistors enable the conguration of an inverter circuit without connecting external input resistors (see equivalent circuit).
* The bias resistors consist of thin-lm resistors with complete isolation to allow negative biasing of the input. They also have the advantage of almost completely eliminating parasitic eects.
* Only the on/o conditions need to be set for operation, making device design easy.
