JIANGSU CHANGJIANG ELECTRONICS TECHNOLOGY CO., LTD Digital transistors (built-in resistors) DTA144EE/DTA144EUA DTA144ECA /DTA144EKA/DTA144ESA DIGITAL TRANSISTOR (PNP) 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 device design easy.
