Features
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 positive 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.
