100mA / 50V Digital transistors

(with built-in resistors)

DTC123EM / DTC123EE / DTC123EUA / DTC123EKA

Applications

Inverter, Interface, Driver

Features

1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see the

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.
