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 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
PIN.
