322 comparator at transmitter end of link drives LED of MCD 2 optoisolator which accepts TTL input. Receiver is similar comparator having additional biasing to match photodiode output of Output optoisolator. Complete system is noninverting,with delay of about 2 μs. Receiver can have any supply within 4.5-40 V range of 322. Transmitter should be matched to its supply voltage by selecting R2 according to equation shown.-W. G. Jung, IC Timer Cookbook, Howard VV. Sams, Indianapolis, IN, 1977, p 156-15.
