zFeatures
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 the device design easy .
