DTA115EKA / DTA115ESA

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 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.
