MAX3094EEPE+

Overview

The MAX3094EEPE+ 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. Propagation delay tolerance is guaranteed within ±10ns across production lots. It includes a low-power shutdown mode with 1nA typical supply current and a fail-safe feature ensuring logic-high output when inputs are open. The component is housed in a 16-pin Plastic DIP package.

Feature Summary

• Integrated ±15kV ESD protection on all receiver inputs for harsh environments
• Guaranteed propagation-delay matching between devices for minimal skew
• Low-power shutdown mode reduces supply current to 1nA
• Fail-safe design guarantees logic-high output during open-circuit conditions

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 'EPE+' corresponds to the -40°C to +85°C temperature range and 16-pin Plastic DIP package configuration. Confirm that the component is sourced directly from Analog Devices or authorized distributors to ensure authenticity. Check for RoHS compliance status as indicated in official documentation before finalizing procurement.

Selection Notes

Select this component when a quad receiver with tight propagation-delay matching is required for multi-drop RS-485 networks. It serves as a pin-compatible upgrade to the industry-standard ’34C86. Ensure the system operates at +3.3V, as this variant differs from the +5V MAX3093E. Verify that the 10Mbps data rate meets application requirements.

Part Context

The MAX3094EEPE+ 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 and propagation delay tolerance specifications.

Replacement Considerations

The MAX3094EEPE+ is a direct pin-compatible replacement for the industry-standard ’34C86. Designers upgrading from legacy components should verify that the new supply voltage and ESD protection levels align with existing circuit designs.
