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 thinfilm resistors with complete isola-tion 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 device design easy.
