100mA / 50V Digital transistors (with built-in resistor) DTC124TM / DTC124TE / DTC124TUA / DTC124TKA Applications Inverter, Interface, Driver 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 the device design easy.
