• High current transfer ratio
• Isolation test voltage, 4000 V
RMS
• Industry standard SOIC-8 surface mountable
package
• 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
DESCRIPTION
The IL215AT/IL216AT/IL217AT are optically coupled pairs
with a Gallium Arsenide infrared LED and a silicon NPN
phototransistor. Signal information, including a DC level, can
be transmitted by the device while maintaining a high degree
of electrical isolation between input and output. The
IL215AT/IL216AT/IL217AT comes in a standard SOIC-8
small outline package for surface mounting which makes it
ideally suited for high density applications with limited space.
In addition to eliminating through hole requirements, this
package conforms to standards for surface mounted
devices.
The high CTR at low input current is designed for low power
consumption requirements such as CMOS microprocessor
interfaces.
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

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation of the device is not implied
at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute maximum ratings for
extended periods of the time can adversely affect reliability.
