MAX14931BASE+

Digital Isolators Overview

The MAX14931BASE+ is a four-channel digital isolator manufactured by Analog Devices Inc. (Maxim Integrated). It features a 3/1 channel configuration and supports data rates up to 25Mbps. The device provides 2.5kVrms isolation voltage with a common-mode transient immunity of 25kV/µs. It operates within a supply voltage range of 1.71V to 5.5V and functions across an extended temperature range of -40°C to +125°C. The component is housed in a 16-SOIC package with a width of 3.90mm.

Digital Isolators Feature Summary

• Provides robust galvanic isolation for high-speed digital signal transmission between isolated circuits.
• Features high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports wide operating supply voltages compatible with various logic families.

Digital Isolators Applications

• Industrial automation systems requiring reliable signal isolation
• Medical equipment needing certified isolation barriers
• Power electronics control interfaces

Digital Isolators Procurement Notes

Verify the specific suffix (+) indicates lead-free compliance when sourcing. Confirm the package variant matches the required footprint, as other suffixes may denote different thermal or mechanical specifications. Ensure the supplier provides official documentation from Analog Devices or Maxim Integrated to guarantee authenticity and traceability.

Digital Isolators Selection Notes

Select this component when a 3/1 channel configuration is required for asymmetric data paths. Compare against the MAX14931CASE+ if higher data rates up to 150Mbps are necessary, noting the difference in speed capabilities. Ensure the 25Mbps rate meets the system's timing requirements before finalizing the design.

Digital Isolators Part Context

This part belongs to the MAX1493x family of digital isolators designed for general-purpose applications. It complements other variants like the MAX14931BAWE, which offers a wider SOIC package, and the MAX14931CASE, which supports higher data speeds. The family focuses on providing reliable isolation in compact form factors.

Digital Isolators Replacement Considerations

The MAX14931CASE+ serves as a higher-speed alternative within the same family. Verify pin compatibility and isolation ratings when substituting with other 16-pin digital isolators from different manufacturers.
