DESCRIPTION
The IS610, IS611 are optically coupled isolators
consisting of infrared light emitting diode and a
symmetrical bilateral silicon photodetector. The
detector is electrically isolated from the input and
performs like an ideal isolated FET designed for
distortion-free control of low level ac and dc
analog signals.The IS610, IS611 are mounted in a
standard 6pin dual in line plastic package.
