The 4N25 is an optocoupler for
general purpose applications. It
contains a light emitting diode
optically coupled to a photo-
transistor. It is packaged in a 6-pin
DIP package and available in wide-
lead spacing option and lead bend
SMD option. Response time, t , is
typically 3 µs and minimum CTR is
20% at input current of 10 mA.
