■ 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.
