IL222AT

Photovoltaic Output

OptocouplerPhotodarlingtonSOIC-8

The IL222AT is a high-gain photodarlington optocoupler in an SOIC-8 package, offering >200% CTR and 4kV isolation, suitable for low-current CMOS/TTL interfacing.

Best for

  • CMOS to LSTTL/TTL interfacing
  • High-density PCB designs

Avoid if

  • High-speed switching applications (darlington output is slower than standard transistors)

Check before use

  • Base connection requirements
  • Thermal derating at high temperatures
