The ISO7421AQDRQ1 from Texas Instruments is a 2-channel digital isolator utilizing capacitive coupling technology. It supports a maximum data rate of 50Mbps and provides a robust isolation rating of 2500Vrms. This general-purpose isolator features a propagation delay of 9 ns typical and a common-mode transient immunity of 25 kV/µs minimum.
The device operates within a temperature range of -40°C to 125°C and is housed in an 8-SOIC package, suitable for surface mount applications. It offers unidirectional channels and a default high output state. The low power consumption, with typical current draw of 1.5 mA per channel, makes it suitable for various digital isolation needs.
Key electrical characteristics include a surge isolation voltage of 4 kVPK and transient isolation voltage of 4242 VPK. The component is designed for reliability with over 25-year isolation integrity at rated voltage. It supports 3.3-V and 5-V supply and logic levels, enabling level translation in mixed-voltage systems.
