The CYPC817(C-TP2) with Optocouplers SOP-4 RoHS is a optocoupler, which is a component made up of a light emitting diode (LED) and a separate photodetector, which is typically a phototransistor, by OCIC. It is designed to provide electrical isolation between two circuits. The CYPC817(C-TP2) with Optocouplers SOP-4 RoHS is a 4-pin package, meaning there are four pins (one for each end of the LED and phototransistor) and it is RoHS compliant meaning that it does not contain any hazardous materials. This optocoupler is rated for a maximum operating temperature of 125°C and a maximum lead temperature of 260°C and can handle a maximum voltage of 50V. Other features of the CYPC817(C-TP2) with Optocouplers SOP-4 RoHS include a low propagation delay, a high CMRR, and an integrated shield.
