The EL452(TA)-G with Optocouplers SOP-4 RoHS is an electronic component manufactured by Everlight. It is a phototransistor output optocoupler that utilizes an infrared LED and a phototransistor to provide electrical isolation between input and output. It is a Surface Mount Device (SMD) with an SOP-4 RoHS package that is used in high voltage, high speed, and high temperature applications. The EL452(TA)-G has a working voltage of 5 to 12V, low capacitance of 0.4 pF, low noise of 1 nA, and a high isolation voltage up to 5,000Vrms. It also offers high-speed switching, fast turn-on time, and high data transfer rate (up to 1 Mbps), making it ideal for digital signal transmission and data interface interconnection.
