Low Cost Dual-In-Line Package
The 4N39, 4N40, CNY30 and CNY34 are optically-coupled isolators consisting
of a Gallium Arsenide infrared emitting diode and light activated silicon
controlled rectifier (SCR) mounted in a standard 6-pin dual-in-line package. Surface Mount Option Available.
All electrical parameters are 100% tested. Specifications are guaranteed to
a cumulative 0.65% AQL.
