Description
The HCPL-817 contains a light emitting diode optically
coupled to a phototransistor. It is packaged in a 4-pin
DIP package and available in wide-lead spacing option
and lead bend SMD option. Input-output isolation
voltage is 5000 Vrms. Response time, t
r
, is typically 4 µs
and minimum CTR is 50% at input current of 5 mA.
