MAX14930CAWE+

Digital Isolators Overview

The MAX14930CAWE+ is a general-purpose digital isolator featuring four independent channels in a unidirectional 4/0 configuration. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 2750Vrms. The device supports data rates up to 150Mbps, with typical propagation delays of 5.1ns and rise/fall times of 2ns. It operates on a single power supply ranging from 1.71V to 5.5V and offers a common-mode transient immunity of 25kV/µs. Packaged in a 16-pin SOIC-Wide (7.50mm width) surface-mount housing, it functions reliably across an industrial temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation via high-speed capacitive coupling technology for robust signal transmission.
• Features a unidirectional 4-channel architecture designed for simple point-to-point data transfer applications.
• Delivers high common-mode transient immunity to maintain signal integrity in electrically noisy environments.

Digital Isolators Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits with high-voltage noise rejection

Digital Isolators Procurement Notes

Verify the specific suffix and package width against your PCB footprint requirements, as variations exist within the MAX14930 family. Confirm that the unidirectional channel configuration aligns with your circuit design needs. Ensure compatibility with the specified 1.71V to 5.5V supply voltage range for both input and output sides. Check for any updated safety certification documents if your application requires specific regulatory compliance approvals.

Digital Isolators Selection Notes

Select this component when a unidirectional data path is sufficient, as it lacks bidirectional capability found in other variants. Consider the 7.50mm SOIC package width for adequate creepage and clearance distances in high-voltage designs. Evaluate the 150Mbps speed limit against your system's timing requirements, noting that lower-speed variants like the MAX14930AAWE+ offer reduced power consumption for slower applications.

Digital Isolators Part Context

This part belongs to the MAX14930 series of digital isolators manufactured by Analog Devices Inc./Maxim Integrated. The series includes various configurations such as bidirectional options and different speed grades. The CAWE+ designation specifically identifies the 150Mbps unidirectional variant in the wide SOIC package, distinguishing it from tape-and-reel versions or narrower package alternatives within the same functional family.

Digital Isolators Replacement Considerations

The MAX14930BASE+T is a similar 4-channel isolator but operates at a lower 25Mbps data rate. For higher speed requirements, verify if the MAX14930CASE+ meets the specific package width constraints. No direct pin-for-pin replacement with identical performance metrics is confirmed in the provided documentation without further datasheet cross-reference.
