MAX3280EAUK/V+T

Overview

The MAX3280EAUK/V+T is a single RS-485/RS-422 receiver designed for high-speed communication. It guarantees data rates up to 52Mbps with a 3V power supply and operates within a 3V to 5.5V voltage range. The device features ±15kV ESD protection, true fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and a -7V to +12V common-mode range. Packaged in a compact 5-pin SOT23, it supports up to 128 receivers on the bus due to its 1/4-unit-load input impedance. This specific variant holds AEC-Q100 automotive qualification.

Feature Summary

• Guaranteed 52Mbps data rate at 3V operation
• True fail-safe architecture prevents undefined states
• Robust ±15kV ESD protection on receiver inputs
• Automotive qualified (AEC-Q100) reliability

Applications

• Clock Distribution
• Telecom Racks
• Base Stations
• Industrial Control
• Local Area Networks
• Automotive

Procurement Notes

Verify the suffix /V indicates automotive qualification and T denotes tape-and-reel packaging. Confirm the component meets AEC-Q100 standards if used in automotive environments. Ensure the ordering code matches the exact pinout and package dimensions required for the target PCB layout.

Selection Notes

Select this part for applications requiring a single receiver with minimal footprint. It is suitable for multidrop clock distribution due to low package-to-package skew. Consider variants like MAX3281E or MAX3283E if an enable pin is needed, or MAX3284E for low-voltage logic compatibility.

Part Context

This component belongs to the MAX328xE family of single receivers from Analog Devices/Maxim Integrated. The family includes variants with enable pins (MAX3281E/MAX3283E) and low-voltage logic support (MAX3284E). All share similar electrical characteristics but differ in pin configurations and specific functional additions.

Replacement Considerations

Direct replacements include other MAX3280E variants such as MAX3280EAUK+T. For non-automotive applications, standard commercial grade parts may be considered if AEC-Q100 compliance is not required.

FAQ

What is the function of the /V suffix in the part number?

The /V suffix denotes that the component is automotive qualified and meets the AEC-Q100 standard.

How does the true fail-safe feature work?

It guarantees a logic-high receiver output when the receiver inputs are opened, shorted, or connected to a terminated bus with all drivers disabled.

What is the maximum data rate supported?

The device guarantees a maximum data rate of 52Mbps even with a 3V power supply.
