MAX3093ECSE+

Overview

The MAX3093ECSE+ 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. Propagation delays are guaranteed within ±8ns tolerance for precise device-to-device matching. It includes a low-power shutdown mode with 1nA typical supply current and a fail-safe feature ensuring logic-high output during open-circuit input conditions. The component utilizes a 16-pin Narrow SO package.

Feature Summary

• Integrated ±15kV ESD protection on all receiver inputs for harsh environment operation
• Guaranteed propagation-delay tolerance of ±8ns between devices across production lots
• Quarter-unit-load input impedance allowing up to 128 receivers on a single bus
• Fail-safe circuitry guarantees a logic-high output when differential inputs are open

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 ordering suffix 'CSE' corresponds to the required temperature range (0°C to +70°C) and the 16-pin Narrow SOIC package configuration. Confirm that the '+T' designation indicates tape-and-reel packaging if reel quantities are required for assembly. Ensure compatibility with existing board layouts designed for the legacy '34C86 standard before finalizing procurement.

Selection Notes

Select this component when a +5V supply voltage is available and high-speed data reception at 10Mbps is required. The MAX3093E is specifically designed as a pin-compatible, low-power upgrade to the industry-standard '34C86 receiver. Choose this part over the MAX3094E variant if the system design mandates a 5V operating voltage rather than the 3.3V requirement of the latter.

Part Context

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

Replacement Considerations

The MAX3093E serves as a direct pin-compatible replacement for the industry-standard '34C86 receiver. Designers upgrading from legacy components should verify that the new propagation delay specifications align with the system timing requirements.
