ISO7221MDRG4-HXY

The ISO7221MDRG4 digital isolator delivers outstanding performance characteristics and reliability, surpassing optocouplers and other digital isolator technologies. This device employs a next-generation intelligent voltage division technique based on capacitive division principles, enabling precise voltage signal transmission across the isolation barrier without modulation or demodulation. Each transmission channel operates independently, supporting multiple transfer direction configurations, with isolation ratings from 1.5kV rms to 5.0kV rms and signal transmission from DC to 600Mbps. It supports 3.0V operation and is compatible with 3.0V to 5.5V logic level translation. When the input-side supply is unpowered or no input signal is present while the output-side supply is active, the isolator output defaults to a defined default logic state.
