IL221AT/222AT/223AT

Vishay Semiconductors

DESCRIPTION

The IL221AT/IL222AT/IL223AT is a high current transfer

ratio (CTR) optocoupler with a gallium arsenide infrared LED

emitter and a silicon NPN photodarlington transistor

detector.

The device has a CTR tested at 1.0 mA LED current. This

low drive current permits easy interfacing from CMOS to

LSTTL or TTL.

This optocoupler is constructed in a standard SOIC-8 foot

print which makes it ideally suited for high density

applications.

In

addition

to

eliminating

through-hole

requirements, this package conforms to standards for

surface mount devices.

FEATURES

• Industry standard SOIC-8 surface mountable

package

• Standard lead spacing, 0.05"

• Available only on tape and reel (conforms to

EIA standard RS481A)

• Compatible with dual wave, vapor phase and IR reflow

soldering

• Lead (Pb)-free component

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

WEEE 2002/96/EC

AGENCY APPROVALS

• UL1577, file no. E52744 system code Y

• CUL - file no. E52744, equivalent to CSA bulletin 5A

• DIN EN 60747-5-5 available with option 1
