Description
The 4N35 is an optocoupler for general purpose applica-
tions. It contains a light emitting diode optically coupled
to a photo-transistor. It is packaged in a 6-pin DIP pack-
age and available in wide-lead spacing option and lead
bend SMD option. Response time, tr, is typically 3 µs and
minimum CTR is 100% at input current of 10 mA.
Applications
I/O interfaces for computers
System appliances, measuring instruments
Signal transmission between circuits of different
potentials and impedances
