JIANGSU CHANGJIANG ELECTRONICS TECHNOLOGY CO., LTD Digital transistors (built-in resistors) DTA143ZE/ DTA143ZUA/ DTA143ZCA/DTA143ZKA/DTA143ZSA 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.
