Features
•
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 negative 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
.
•
