MAX14930AASE+T

Overview

The MAX14930AASE+T is a general-purpose digital isolator manufactured by Analog Devices Inc./Maxim Integrated. It features four unidirectional channels with a data rate of 1Mbps and an isolation voltage of 2750Vrms. The device utilizes capacitive coupling technology and operates within a supply voltage range of 1.71V to 5.5V. It is housed in a 16-SOIC package (0.154 inch width) and supports surface mount installation. The component functions across an operating temperature range of -40°C to +125°C, ensuring reliability in industrial environments.

Feature Summary

• Provides galvanic isolation across four independent unidirectional channels
• Utilizes capacitive coupling technology for signal transmission
• Supports wide supply voltage operation from 1.71V to 5.5V
• Designed for high-temperature industrial applications up to 125°C

Applications

• Industrial process control systems requiring channel isolation
• Measurement and sensing equipment interfaces
• General-purpose digital communication isolation
• Microcontroller peripheral isolation in harsh environments

Procurement Notes

Verify the specific suffix 'AASE+T' to confirm the tape-and-reel packaging configuration and the 'AA' grade specifications. Ensure compatibility with 16-SOIC footprint requirements during PCB layout. Confirm RoHS compliance status as indicated by the '+' suffix in official documentation before finalizing procurement orders.

Selection Notes

Select this component when four isolated unidirectional channels are required at lower data rates. The 1Mbps speed suits most standard digital interfaces. Consider the 16-SOIC narrow package for space-constrained designs. Verify that the 2750Vrms isolation rating meets system safety standards. Evaluate power consumption against available supply rails within the 1.71V to 5.5V range.

Part Context

This part belongs to the MAX1493x family of digital isolators from Maxim Integrated, now part of Analog Devices. The family includes variants with different channel counts, data rates, and isolation voltages. The MAX14930 specifically offers four channels at 1Mbps, distinguishing it from higher-speed or multi-configurations within the same series.
