IL255 - BIDIRECTIONAL INPUT OPTOCOUPLER

General Description

The IL255 is a bidirectional input optically coupled isolator consisting of two high current Gallium Arsenide infrared LEDs coupled to a silicon NPN phototransistor.

The IL255 has a minimum CTR of 20% This optocoupler is ideal for applications requiring AC signal detection and monitoring.

Key Features

  • AC or Polarity Insensitive Inputs.
  • Continuous Forward Current, 130 mA.
