DTC144TUA SOT-323 DIGITAL TRANSISTORS TRANSISTORS (NPN) 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. SOT-323 * Only the on/off conditions need to be set for operation marking device design easy.
