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.

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.

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)

• Lead (Pb)-free component

• Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC

APPLICATIONS

• Telecom applications ring detection
