MAX3094ECUE+

Overview

The MAX3094ECUE+ is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +3.3V 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-TSSOP package and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Provides robust electrostatic discharge protection for harsh environments
• Ensures precise timing with guaranteed propagation-delay matching across production lots
• Supports high bus density through quarter-unit-load input impedance
• Enables ultra-low power consumption via dedicated shutdown mode

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 'C' corresponds to the commercial temperature range (0°C to +70°C) rather than the extended range (-40°C to +85°C). Confirm the '+T' or standard tape-and-reel packaging requirements against current distributor specifications. Ensure the component source matches the official Analog Devices or Maxim Integrated manufacturing records to avoid counterfeit parts.

Selection Notes

Select this component when a 3.3V supply voltage is required instead of the 5V variant (MAX3093E). Choose this part for designs requiring strict propagation delay matching between multiple devices on the same bus. It serves as a direct pin-compatible upgrade to the industry-standard SN75174 or '34C86 families while offering lower power consumption.

Part Context

This device belongs to the MAX3093E/MAX3094E family of rugged, low-power quad receivers. While the MAX3093E operates at 5V, the MAX3094E is optimized for 3.3V systems. Both share identical pinouts and functional characteristics, differing primarily in supply voltage requirements and specific propagation delay tolerances defined in their respective datasheet sections.

Replacement Considerations

The MAX3093ECUE+ serves as a compatible alternative if the system design allows for a +5V supply voltage instead of +3.3V. Both components are pin-compatible and function as low-power upgrades to legacy '34C86 transceivers.
