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 thinfilm 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.
