Overview
The ADUM6421AWBRNZ5-RL is a quad-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides four data channels with a 3:1 direction configuration (three inputs to one output). The device supports data rates up to 100 Mb/s and offers a common-mode transient immunity of 75 kV/µs. It operates within a supply voltage range of 4.5 V to 5.5 V and includes a shutdown function. Packaged in a 28-pin SOIC, it functions reliably between -40°C and +125°C.
Feature Summary
- Integrates an isolated DC-to-DC converter for power delivery across the isolation barrier
- Provides high common-mode transient immunity for noise-resistant signal transmission
- Includes a dedicated shutdown pin for power management control
Applications
- Industrial automation systems requiring galvanic isolation
- Medical equipment needing reliable signal separation
- Automotive electronics interfaces
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix AWBRNZ5-RL matches design requirements. Check current availability status as supply may be limited. Ensure proper handling procedures are followed during installation to maintain isolation integrity.
Selection Notes
Select this component when a 3:1 data direction is required alongside integrated isolated power. Compare against other ADuM642x variants if different channel configurations like 2:2 or 1:3 are needed. Evaluate thermal performance within the SOIC-28 package constraints for the target application environment.
Part Context
This part belongs to the ADuM642xA family of quad-channel digital isolators. These devices combine high-speed signal isolation with integrated power conversion, simplifying board design by eliminating external isolated power supplies. The family includes variants with different data directions and packaging options.
Replacement Considerations
Consider ADUM6421ABRNZ5-RL for similar functionality. Verify that alternative packages or suffixes meet all electrical and mechanical specifications before substitution.
