Features
1) Built-in circuit enables 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 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.
