zFeatures

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 the device design easy.

4) Higher mounting densities can be achieved.
