JIANGSU CHANGJIANG ELECTRONICS TECHNOLOGY CO., LTD Digital transistors (built-in resistors) DTC123YE/DTC123YUA/ DTC123YKA/DTC123YCA / DTC123YSA DIGITAL TRANSISTOR (NPN) 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.
