DESCRIPTION

The IL205AT/206AT/207AT/208AT 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 IL205/6/7/8

come in a standard SOIC-8 small outline package

for surface mounting which makes them ideally

suited for high density applications with limited

space. In addition to eliminating through-holes

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

a higher safety margin compared to the industry

standard 30 volts.
