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.
