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.
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
