MAX3094EESE

Overview

The MAX3094EESE 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 narrow SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

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

Applications

• Telecommunications equipment interfaces
• Rugged RS-422/RS-485/RS-423 bus receivers
• Receivers for ESD-sensitive applications
• Level translators in mixed-voltage systems

Procurement Notes

Verify the specific ordering suffix 'EESE' corresponds to the required -40°C to +85°C temperature grade and 16-pin narrow SOIC package configuration. Confirm that the component source matches the official Analog Devices or Maxim Integrated specifications to ensure functional integrity and compliance with the documented electrical characteristics.

Selection Notes

Select this component when a low-voltage 3.3V operation is required for RS-422 or RS-485 networks. It is suitable for designs needing high ESD immunity and precise signal synchronization across multiple channels. Consider the narrow SOIC package constraints for PCB layout and verify that the 10Mbps data rate meets the system throughput requirements.

Part Context

This part 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 devices. The MAX3094E variant specifically targets 3.3V systems, distinguishing it from the MAX3093E which operates at 5V.

Replacement Considerations

The MAX3093E is a compatible alternative for 5V systems. For legacy replacements, the '34C86 is functionally similar but lacks the integrated ESD protection and low-power shutdown features.
