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.
