DTA144VUA / DTA144VKA / DTA144VSA

Transistors

Digital transistor (built-in resistors)

DTA144VUA / DTA144VKA / DTA144VSA

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 positive biasing of the input,
and parasitic effects are almost completely eliminated.

3) Only the on / off conditions need to be set for
operation, making device design easy.

4) Higher mounting densities can be achieved.
