zFeatures
1) Built-in bias resistors enable 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 isolati on to allo w 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.
