Applications
Inverter, Interface, Driver
Features
1) Built-in bias resistors enable the co nfiguration of an inverter circuit without connecting external input resistors (see
equivalent circuit).
2) The bias resistors consist of thin-film resist ors 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.
