IL256AT - Optocoupler

Description

The IL256AT is an AC input phototransistor optocoupler.

The device consists of two infrared emitters connected in reverse parallel and coupled to a silicon NPN phototransistor detector.

These circuit elements are constructed with a standard SOIC-8 foot print.

Features

  • Guaranteed CTR symmetry, 2:1 maximum.
  • Bidirectional AC input industry standard SOIC-8 surface mountable package.
  • Isolation test voltage, 4000 VRMS.
  • Standard lead.
  • spacing, 0.05".
  • Available only on tape and reel (conform to EIA standard RS481A).
  • Material categorization: for definitions of compliance please see www. vishay. com/doc?99912.

The device consists of two infrared emitters connected in reverse parallel and coupled to a silicon NPN phototransistor detector. These circuit elements are constructed with a standard SOIC-8 foot print. The product is well suited for telecom applications such as ring detection or off / on hook status, given its bidirectional LED input and guaranteed current transfer ratio (CTR) minimum of 20 % at IF = 10 mA.
