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

FEATUREs
•  Current Transfer Ratio (CTR: min. 50% at IF = 5 mA, VCE = 5 V)
•  High input-output isolation voltage (Viso = 5000 Vrms)
•  Response time (tr: typ., 4 µs at VCE = 2 V, IC = 2 mA, RL = 100 Ω)
•  Compact dual-in-line package
•  UL approved
•  CSA approved
•  IEC/EN/DIN EN 60747-5-2 approved
•  Options available:         
–  Leads with 0.4" (10.16 mm) spacing (W00)   
–  Leads bends for surface mounting (300)
  –  Tape and reel for SMD (500)       
–  IEC/EN/DIN EN 60747-5-2 approvals (060)

APPLICATIONs
•  Signal transmission between circuits of different  potentials and impedances
•  I/O interfaces for computers
•  Feedback circuit in power supply
