MAX3094EEUE+T

Overview

The MAX3094EEUE+T is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3V to +3.6V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via Human Body Model, ±8kV IEC 1000-4-2 Contact Discharge, and ±15kV Air-Gap Discharge. It includes a 1nA low-power shutdown mode and guarantees propagation-delay matching within ±10ns. The unit utilizes a 16-pin TSSOP package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• High electrostatic discharge protection on all receiver inputs for harsh environments
• Guaranteed propagation-delay matching between devices across production lots
• Low-power shutdown mode with high-impedance outputs and minimal current draw
• Quarter-unit-load input impedance allowing extensive bus configurations

Applications

• Telecommunications equipment
• Rugged RS-422/RS-485/RS-423 bus receivers
• Receivers for ESD-sensitive applications
• Level translators

Procurement Notes

Verify the specific ordering suffix EEUE corresponds to the extended temperature range (-40°C to +85°C) and the 16-pin TSSOP package configuration. Confirm that the '+T' designation indicates tape-and-reel packaging as specified in the manufacturer's documentation. Ensure compatibility with the required +3V logic supply voltage before finalizing procurement.

Selection Notes

Select this component when designing systems requiring quad differential receivers for RS-422 or RS-485 networks. It is suitable for applications needing tight propagation delay matching to minimize skew between multiple data lines. Choose this part over the MAX3093E if the system operates exclusively on a +3.3V supply rather than +5V.

Part Context

This device belongs to the MAX3093E/MAX3094E family of low-power, rugged quad receivers. It serves as a pin-compatible, low-power upgrade to the industry-standard '34C86. The MAX3094E variant specifically targets +3V operation, distinguishing it from the +5V MAX3093E, while sharing identical functional characteristics and package options.

Replacement Considerations

The MAX3093E is a compatible alternative for +5V systems. For legacy replacements, consider the '34C86, though power consumption will differ. Verify pin compatibility and voltage levels when substituting.
