DTC144TM / DTC144TE / DTC144TUA / DTC144TKA are a series of digital transistors manufactured by ROHM. This transistor features 1)Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see equivalent circuit). 2)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. 3)Only the on/off conditions need to be set for operation, making the device design easy.
The ROHM DTC144TUA is a 100 mA / 50 V digital transistor with a built‑in bias resistor, designed for inverter, interface and driver applications. The datasheet provides features, structure, dimensions, packaging options and electrical ratings.
Key sections include absolute maximum ratings, electrical characteristics, characteristic curves and a notice on usage and export restrictions. The document is intended for designers integrating the device into general‑use electronic equipment.
