Transistors Digital transistors (built in resistor) DTB143TK / DTB143TS 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 thinfilm resistors with complete isolation to allow positive 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.
