DESCRIPTION
The IL205AT/IL206AT/IL207AT/IL208AT 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. This family comes in a standard SOIC-8A small
outline package for surface mounting which makes them
ideally suited for high density application with limited space.
In addition to eliminating through-hole requirements, this
package conforms to standards for surface mounted
devices.
A specified minimum and maximum CTR allows a narrow
tolerance in the electrical design of the adjacent circuits. The
high BV
CEO
of 70 V gives a higher safety margin compared
to the industry standard 30 V.
• UL1577, file no. E52744 system code Y
• CUL - file no. E52744, equivalent to CSA bulletin 5A

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.
