Application Scenarios & Design Considerations

Optocoupler, Photodarlington Output, Dual Channel, SOIC-8 package

Alternative Part Number

  • LTV-827 --: Dual-channel optocoupler with similar CTR and isolation ratings, pin-compatible in most circuits and widely available.
  • PC817X2 --: Dual optocoupler in a DIP-8 package offering comparable current transfer ratio and isolation voltage for signal isolation.
  • TLP281-2 --: Two-channel phototransistor optocoupler with similar CTR range and 5 kV isolation, suitable as a functional replacement.
  • LTV-827S --: Dual-channel optocoupler in SOP-8 with similar CTR and isolation ratings, a common drop-in replacement for the ILD223T in many designs.
  • PC817X2NSZ0F --: Dual optocoupler in a surface-mount package with comparable current transfer ratio and isolation voltage, widely available and cost-effective.
