MAX3295AUT+

Overview

The MAX3295AUT+ is a low-power, high-speed RS-485/RS-422 transmitter operating from a single +3.3V supply. It features one differential driver capable of data rates up to 20Mbps with an output skew of less than 5ns and guaranteed propagation delay below 25ns. The device draws 5mA in normal operation and 1µA in shutdown mode. It includes hot-swap inputs, current limiting, and thermal shutdown protection. Packaged in a space-saving 6-pin SOT23, it operates over the automotive temperature range of -40°C to +125°C.

Feature Summary

• Hot-swap input circuitry prevents false transitions during board insertion or connection to live backplanes
• Integrated short-circuit current limiting and thermal-shutdown circuitry protect against excessive power dissipation
• Low-power shutdown mode reduces supply current to 1µA when driver enable is pulled low

Applications

• RS-485/RS-422 Communications
• Clock Distribution
• Telecom Equipment
• Automotive Systems
• Security Equipment
• Point-of-Sale Equipment
• Industrial Control

Procurement Notes

Verify the component authenticity by checking the top marking for ABNK or ABVJ codes corresponding to the MAX3295AUT+ variant. Confirm the package type is 6-pin SOT23 and ensure the suffix indicates lead-free/RoHS compliance. Cross-reference the manufacturer part number with official Analog Devices documentation to validate specifications before integration into designs.

Selection Notes

Select this component when a compact, single-driver solution is required for RS-485 or RS-422 networks. It is suitable for applications needing high-speed transmission up to 20Mbps without slew-rate limiting. Ensure the design accommodates the 6-pin SOT23 footprint and operates within the specified -40°C to +125°C temperature range.

Part Context

This device belongs to the MAX329x family of low-power transmitters designed for RS-485/RS-422 communication. Unlike the MAX3293 and MAX3294, which feature slew-rate limiting to minimize EMI, the MAX3295 provides full-speed performance up to 20Mbps. All variants share the same 6-pin SOT23 package and operate from a single +3.3V supply.

Replacement Considerations

MAX3295AUT/V+T is an AEC-Q100 qualified automotive version of this component.
