MAX3093ECSE

Overview

The MAX3093ECSE is a low-power, 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 1nA shutdown mode, fail-safe logic-high output for open inputs, and a quarter-unit-load input impedance allowing up to 128 receivers on the bus. The component is housed in a 16-pin Narrow SO package.

Feature Summary

• Integrated ±15kV ESD protection on all receiver inputs for harsh environments
• Guaranteed propagation-delay tolerance of ±8ns between devices
• Quarter-unit-load input impedance supporting up to 128 receivers per 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 'CSE' corresponds to the commercial temperature range (0°C to +70°C) and the 16-pin Narrow SOIC package. Confirm that the '+T' designation indicates tape-and-reel packaging if required for automated assembly. Ensure the datasheet revision matches the design requirements for electrical characteristics and pinout compatibility.

Selection Notes

Select this component when a dedicated quad receiver with high ESD immunity is required for RS-422 or RS-485 networks. It serves as a direct pin-compatible upgrade to the industry-standard '34C86. Choose this part over the MAX3094E variant specifically because the system design mandates a +5V operating voltage rather than the 3.3V supply used by the MAX3094E.

Part Context

This device belongs to the MAX3093E/MAX3094E family of rugged, low-power quad receivers. The MAX3093E is distinguished by its +5V operation, whereas the MAX3094E operates at +3.3V. Both share identical pinouts and functional features, differing primarily in supply voltage and propagation delay matching specifications.

Replacement Considerations

The MAX3093ECSE is a pin-compatible, low-power upgrade to the industry-standard '34C86. Designers replacing legacy components should verify that the new ESD protection levels and input impedance characteristics meet the system's noise immunity and bus loading requirements.
