FEATURES
*Built-in bias resistors enable the configuration of an inverter
circuit without connecting external input resistors.(see equi-
valent circuit).
*Only the on/off conditions need to be set for operation mark-
ing device design easy.
*The bias resistors consist of thin-film resistors with co-
mplete isolation to allow negative biasing of the input.
They also have the advantage of almost completely El-
iminating parasitic effects.
MECHANICAL DATA
* Case: Molded plastic
* Epoxy: UL 94V-O rate flame retardant
* Lead: MIL-STD-202E method 208C guaranteed
* Mounting position: Any
* Weight: 0.009 gram
