MAX3295AUT+T

Overview

The MAX3295AUT+T is a low-power, high-speed RS-485/RS-422 transmitter manufactured by Maxim Integrated. It operates from a single +3.3V supply and supports data rates up to 20Mbps with an output skew of less than 5ns and driver propagation delay below 25ns. The device draws 5mA in normal operation and 1µA in shutdown mode. It features hot-swap circuitry, short-circuit current limiting, and thermal shutdown protection. Qualified under AEC-Q100 for automotive applications, it functions within the -40°C to +125°C temperature range and is housed in a compact 6-pin SOT23 package.

Feature Summary

• Hot-swap input capability prevents false transitions during live backplane connection
• Integrated short-circuit current limiting and thermal-shutdown protection
• Automotive-grade qualification compliant with AEC-Q100 standards

Applications

• RS-485/RS-422 Communications
• Telecom Equipment
• Automotive Systems
• Industrial Control

Procurement Notes

Verify that the ordering suffix includes 'T' to confirm tape-and-reel packaging configuration. Confirm the '+A' or 'V' designation indicates AEC-Q100 automotive qualification if required for the specific application environment. Ensure the component source matches the official manufacturer specifications.

Selection Notes

Select this model when high-speed transmission up to 20Mbps is required without slew-rate limitations. It is suitable for environments requiring robust protection against bus contention and hot-plugging events. Consider alternative models like the MAX3293 or MAX3294 only if lower data rates are acceptable to minimize electromagnetic interference through slew-rate limiting.

Part Context

This component belongs to the MAX329x family of single transmitters designed for balanced communication networks. Unlike the MAX3293 and MAX3294 variants which feature slew-rate limiting, the MAX3295 provides maximum speed performance. The AUT suffix specifically denotes the automotive temperature range extension and reliability standards.

Replacement Considerations

The MAX3295AUT/V+T serves as a confirmed automotive-qualified substitute variant within the same series.
