IL256A - AC INPUT PHOTOTRANSISTOR SMALL OUTLINE SURFACE MOUNT OPTOCOUPLER

General Description

The IL256A is an AC input phototransistor optocoupler.

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

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

Key Features

  • Guranteed CTR Symmetry, 2:1 Maximum.
  • Bidirectional AC Input Industry Standard SOIC-8 Surface.
  • Mountable Package.
  • Standard Lead Spacing, .05".
  • Available in Tape and Reel Option (Conforms to EIA Standard RS481A).

IL256A EW FEATURES • Guranteed CTR Symmetry, 2:1 Maximum • Bidirectional AC Input Industry Standard SOIC-8 Surface • Mountable Package • Standard Lead Spacing, .05" • Available in Tape and Reel Option (Conforms to EIA Standard RS481A) DESCRIPTION The IL256A is an AC input phototransistor optocoupler. The device consists of two infrared emitters connected in anti-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.
