    • 1)Built-in bias resistors enable the configuration of an invertercircuit without connecting external input resistors(see equivalent circuit)
    • 2)The bias resistors consist of thin-film resistors with complete isolation to allow 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 desigh easy.
