100mA / 50V Digital transistors

(with built-in resistors)

DTC143EM / DTC143EE / DTC143EUA / DTC143EKA



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.
