FEATURES
* Built-in bias resistors enable the configuration of an inverter
   circuit without connecting external input resistors (see
   equivalent circuit).
* 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.
* Only the on/off conditions need to be set for operation,
   making device design easy.
