Description
Features
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, tr, is typically 4 μs and minimum
CTR is 50% at input current of 5 mA.
