Features
1) Built-in bias resistors enable the configuration of an inverter cir-
cuit without connecting external input resistors (see equivalent
circuit).
2) The bias resistors consist of thinfilm resistors with complete
isolation to allow positive biasing of the input. They also have the
advantage of almost completely eliminat-ing parasitic effects.
3) Only the on/off conditions need to be set for operation, making
device design easy.
