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 positive biasing of the 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
