FEATURES
* Built-in bias resistors enable the configuration of
   an inverter circuit without connecting input resistors
   (see equivalent circuit).
* Only the on/off confitions need to be set for operation,
   making device design easy.
* The bias resistors consis of thin-film resistors with
   compete isolation to allow negative biasing of the
   input. They also have the advantage of almost
   completely eliminating parasitic effects.
