The CYTLP185(GB-TP) with Optocouplers SOP-4 RoHS is a surface-mount optocoupler manufactured by OCIC. It is a quad channel optocoupler with 4 isolated channels and is designed for use in signal transmission and isolation between two circuits. It features a low power consumption of 90 mA maximum at a 3.75 VDC input. The coupling of each channel is an infrared LED and an integrated photodetector. It has a high common mode transmittance rate of up to 2500V/µs, and a high isolation voltage of up to 3750VRMS. It also features an optimal operating frequency of 30kHz, making it suitable for use in a wide variety of applications. It is RoHS compliant and has a compact SOP-4 package, making it easy to place on a printed circuit board.
