zFeatures
1) Built-in bias resistors enable the configuratio n 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 the device design easy.
