MAX14930AASE+

Overview

The MAX14930AASE+ is a general-purpose digital isolator manufactured by Analog Devices Inc./Maxim Integrated. It provides galvanic isolation up to 2750Vrms across four channels with a data rate of 1Mbps and a typical common-mode transient immunity (CMTI) of 25kV/µs. The device operates on a supply voltage range of 1.71V to 5.5V and features unidirectional channel configuration. It is housed in a 16-SOIC package with a width of 3.90mm and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Provides robust galvanic isolation for signal transmission between circuits
• Utilizes capacitive coupling technology for high-speed digital communication
• Features unidirectional data flow across all four isolated channels

Applications

• Industrial automation systems requiring signal isolation
• Medical equipment needing safe patient isolation barriers
• Power electronics control interfaces

Procurement Notes

Verify the specific suffix 'AASE' against official datasheets to confirm the 1Mbps data rate variant, as other suffixes may indicate different speeds. Ensure the SOIC-16 package dimensions match your PCB footprint requirements. Confirm RoHS compliance status through the manufacturer's certification documents before finalizing procurement orders.

Selection Notes

Select this component when a low-speed, cost-effective isolation solution is required for four-channel applications. The 1Mbps data rate suits most standard industrial protocols. Consider the wide supply voltage range for compatibility with various logic levels. Evaluate the thermal performance within the specified temperature range for your specific enclosure environment.

Part Context

This part belongs to the MAX1493x family of digital isolators, which offers various speed grades and channel configurations. The MAX14930 specifically denotes the 1Mbps variant within this series. These devices are designed to replace traditional optocouplers in modern designs, offering superior performance in terms of speed, power consumption, and reliability while maintaining small form factors.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX1493x family that offer higher data rates if system requirements change. Verify that any substitute maintains the same 2750Vrms isolation rating and SOIC-16 package type to ensure mechanical compatibility.
