Features
1) Built-in bias resistors enable the configuration of an
   inverter circuit without connecting external input resistors.
2) The bias resistors consist of thinfilm resistors with complete
   isolation to allow negative biasing of the input. They
   have the advantage of almost completely eliminating parasitic effects.
3) Only the on/off conditions need to be set for operation,
   making device design easy.
4) Pb-Free package is available.
