ROHM DTC144VUA, DTC144VSA, DTC144VKA Datasheet

DTC144VUA / DTC144VKA / DTC144VSA

Transistors

Digital transistor (built-in resistors)

DTC144VUA / DTC144VKA / DTC144VSA

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 device design easy.

4) Higher mounting densities can be achieved.
