DESCRIPTION
The 110 °C 1206AT, 1207AT, 1208AT 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-8 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 BVCEO of 70 V gives a higher safety margin compared
to the industry standard 30 V.
