DTC144TKA / DTC144TSA

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 device design easy.
