zFeatures
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 thin film resistors
with complete isolation 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 device design easy.
