ADUM141D1BRWZ

Digital Isolators Overview

The ADUM141D1BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration (three forward, one reverse) with unidirectional signal flow. Key electrical parameters include a data rate of 150 Mb/s, isolation voltage of 3750 Vrms, and common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.7 V to 5 V, drawing 11.4 mA typical current. Propagation delay is 15 ns, with rise/fall times of 2.5 ns. It functions within an ambient temperature range of -40°C to +125°C and is housed in a 16-lead SOIC package.

Digital Isolators Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the tube packaging format and lead-free RoHS compliance status. Ensure the order matches the 3:1 channel directionality requirement. Confirm that the 16-SOIC footprint aligns with the target PCB design constraints before finalizing procurement.

Digital Isolators Selection Notes

Select this component when high-speed bidirectional or asymmetric data transfer is required across isolated boundaries. The 3750 Vrms insulation rating suits applications demanding strong safety barriers. Consider the 1.7 V minimum supply voltage for compatibility with low-power logic families.

Digital Isolators Part Context

This part belongs to the ADuM141D series of general-purpose digital isolators from Analog Devices. It represents the industry-standard iCoupler architecture, offering a compact alternative to traditional optocouplers by integrating coil technology directly into the silicon substrate for superior performance consistency.

Digital Isolators Replacement Considerations

Public documentation identifies ADUM141D0BRWZ as a related variant within the same family. Verify channel directionality differences between the D0 and D1 suffixes before substitution.
