| DTB122JK Transistors Digital transistor (built-in resistors) DTB122JK Features 1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors. 2) The bias resistors consist of thin-film resistors with complete isolation to allow positive biasing of the input, and parasitic effects are almost completely eliminated. 3) Only the on / off conditions need to be set for operation, making device design easy. 4) Higher mounting densities can be achieved.
