Transistors Digital transistors (built-in resistors) DTA143XE / DTA143XUA / DTA143XKA / DTA143XSA FFeatures FExternal dimensions (Units: mm) 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 isola- tion to allow positive biasing of the input. They also have the advan- tage of almost completely eliminat- ing parasitic effects. 3) Only the on/off conditions need to be set for operation, making device design easy.
