DESCRIPTION

The 66228 optocoupler consists of an 850 nm GaAlAs LED optically coupled to a silicon planar phototransistor. This LED

has proven to be highly tolerant to proton radiation and to be more tolerant of operating temperatures over 100°C than the

more commonly used 660 nm LED. The optocoupler is built on a TO-72 header. The anode of the LED is electrically

connected to the case. The internal base connection has been eliminated for improved noise immunity.
