MAX3093EEUE

Overview

The MAX3093EEUE+ is a quad RS-422/RS-485 receiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and supports data rates up to 10Mbps. The device features ±15kV ESD protection via IEC 1000-4-2 Air-Gap Discharge, ±8kV Contact Discharge, and Human Body Model standards. It includes a low-power shutdown mode with typical supply current of 1nA and an operating supply current of 2.4mA. Propagation delay tolerance is guaranteed within ±8ns. The component is housed in a 16-pin TSSOP package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrated ±15kV ESD protection on all receiver inputs for harsh environments
• Guaranteed propagation-delay matching between devices across production lots
• Quarter-unit-load input impedance allowing up to 128 receivers on a bus
• Fail-safe feature ensuring logic-high output when inputs are open circuit

Applications

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

Procurement Notes

Verify the specific suffix 'EEUE+' against official documentation to confirm the extended temperature range (-40°C to +85°C) and TSSOP-16 packaging. Ensure compatibility with existing board layouts as this device serves as a pin-compatible upgrade to the industry-standard '34C86. Cross-reference datasheet revision dates to validate electrical characteristics before finalizing procurement specifications.

Selection Notes

Select the MAX3093EEUE+ when a +5V supply voltage is required for RS-422 or RS-485 interfaces. This model is appropriate for designs needing high ESD immunity and precise propagation delay matching. Consider the MAX3094E variant if the system operates exclusively on a +3.3V supply. Evaluate the shutdown current requirements, as this device offers a 1nA low-power standby mode suitable for battery-operated or power-constrained applications.

Part Context

The MAX3093E/MAX3094E family consists of rugged, low-power quad receivers designed for RS-422 and RS-485 communication standards. These components provide enhanced electrostatic discharge protection compared to legacy devices. They serve as direct pin-compatible replacements for the industry-standard '34C86, facilitating easier upgrades in existing telecommunications and industrial control hardware without requiring significant schematic modifications.

Replacement Considerations

The MAX3093EEUE+ is explicitly documented as a pin-compatible, low-power upgrade to the industry-standard '34C86. Designers replacing older discrete solutions or legacy ICs should verify that the new device's +5V operation aligns with the existing power rails.
