Description
The CNG/CNX Series are optically coupled isolators consisting of a Gallium Arsenide
infrared emitting diode and an NPN silicon phototransistor mounted in a standard 6-pin dual-
in-line package. Surface Mount Option Available.
All electrical parameters are 100% tested by manufacturing. Specifications are guaranteed to a
cumulative 0.65% AQL
