MAX3094EESE+

Overview

The MAX3094EESE+ is a low-power, 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 IEC 1000-4-2 Air-Gap Discharge, ±8kV Contact Discharge, and Human Body Model standards. It includes a 1nA shutdown mode and guarantees propagation-delay tolerance within ±10ns for device-to-device matching. The component is housed in a 16-pin Narrow SO package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides robust electrostatic discharge protection on all receiver inputs for harsh environments
• Features guaranteed propagation-delay tolerance ensuring precise device-to-device matching across production lots
• Includes a low-power shutdown mode that reduces supply current to approximately 1nA with high-impedance outputs
• Offers fail-safe functionality that guarantees a logic-high output when the differential input is open circuit

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 against official documentation to confirm package type and temperature grade. Confirm RoHS compliance status through manufacturer datasheets or authorized distributors. Ensure the procurement channel provides valid traceability for industrial-grade components.

Selection Notes

Select this component for designs requiring low-voltage operation at 3.3V with high noise immunity. The tight propagation delay matching makes it suitable for multi-drop buses where signal skew must be minimized. Verify that the narrow SO package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the MAX3093E/MAX3094E family of rugged, low-power 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, whereas the MAX3093E is designed for 5V supplies.

Replacement Considerations

The MAX3094EESE+ is a direct pin-compatible replacement for the '34C86 series. For 5V applications, the MAX3093E series may be considered if voltage requirements differ.
