!Features
1) Built-in bias resistors enable the
configuration of an inverter circuit
without connecting external input
resistors (see the equivalent
circuit).
2) The bias resistors consist of thin-
film resistors 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
device design easy.
