zFeatures
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 the device design easy .
