Package.
The CQ680 is an optically coupled isolator 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.
