The OCIC CYTLP785(GB-TP2) is a 4-pin SOP Optocoupler in RoHS compliant packaging and is designed to provide isolation of a digital signal from the input to the output. The device is composed of an infrared LED radiated by a phototransistor in an all-packaged module. It is constructed with the latest gallium-arsenide phosphide LED and high-gain phototransistor technology, and features a wide current transfer ratio and low frequency response. The CYTLP785(GB-TP2) is suitable for a variety of applications including isolation of a logic signal, current sensing, ARCNET, industrial measurement, garage door entry systems, and optical switching. It is RoHS compliant and provides high insulation resistance to protect against hardware malfunctioning.
