MAX3295AUT/V+T

Overview

The MAX3295AUT/V+T is a low-power, high-speed RS-485/RS-422 transmitter manufactured by Analog Devices Inc./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 during 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 a temperature range of -40°C to +125°C and is housed in a 6-pin SOT23 package.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards
• Integrated hot-swap input circuitry prevents false transitions during live backplane connection
• Built-in short-circuit current limiting and thermal-shutdown mechanisms protect against excessive power dissipation

Applications

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

Procurement Notes

Verify the specific ordering suffix /V+T to confirm AEC-Q100 automotive qualification and lead-free status. Ensure the component matches the required 6-pin SOT23 package dimensions and thermal characteristics for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to validate electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when designing systems requiring high-speed differential transmission up to 20Mbps in space-constrained environments. It is suitable for applications needing robust protection against bus contention and hot-plugging events. Consider the 6-pin SOT23 footprint for compact designs and verify that the operating voltage aligns with the specified +3.3V requirement.

Part Context

This part belongs to the MAX3293/MAX3294/MAX3295 family of low-power transmitters. While the MAX3293 and MAX3294 feature slew-rate limiting for EMI reduction at lower speeds, the MAX3295 provides full 20Mbps performance without such limitations. The AUT/V+T designation specifically denotes the automotive-qualified variant within this series.

Replacement Considerations

The MAX3295AUT+T serves as a non-automotive equivalent within the same family. Verify if AEC-Q100 certification is strictly required for the application before substituting.
