zApplica tions

Inverter, Interface, Driver

zFeatures

1) Built-in bi as resistors enable the configuration of an inverter circuit without connecting external input resistors (see
equivalent circuit).

2) The bias resistors consist of thin-film resistors with complete isol ation to allow negative 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 .
