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 the device design easy.

4)Higher mounting densities can be achieved.
