100mA / 50V Digital transistor

(with built-in resistors)

DTC144VUA / DTC144VKA

Applications

Inverter, Interface, Driver

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 negative biasing of

the input, and parasitic effects are almost completely

eliminated.

3) Only the on / off conditions need to be set

for operation, making the device design easy.

4) Higher mounting densities can be achieved.
