CS5242CM is a galvanically isolated and optically coupled isolator from Infineon. It is a part of the CS5200Isolator family, designed to protect low-voltage interfaces from high-voltage and electromagnetic noise. This device is a single channel digital isolator with an electrical isolation rating of 5 kV that provides an optically independent path of data transfer with a wide common mode transient immunity range of 2000 V/µs. The CS5242CM features a highly reliable MOSFET output with low quiescent current and high common mode transient immunity range, making it suitable for capacitive loads. Additionally, it is able to operate over a temperature range between -40°C and +125°C. It supports a supply voltage range of 2.5 - 10 V and features an integrated rise time filter, in order to reduce the effects of high-frequency noise.
