MAX3093ECUE+T

Overview

The MAX3093ECUE+T 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 matching across production lots. It includes a low-power shutdown mode with typical current draw of 1nA and an operating supply current of 2.4mA. The component utilizes a 16-pin TSSOP package and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Integrated ±15kV ESD protection on all receiver inputs for harsh environments
• Guaranteed propagation-delay matching between devices within ±8ns tolerance
• Quarter-unit-load input impedance allowing up to 128 receivers on a bus
• Fail-safe feature ensuring logic-high output when inputs are 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 suffix 'T' indicates tape-and-reel packaging configuration. Confirm that the 'C' designation corresponds to the commercial temperature range of 0°C to +70°C. Ensure compatibility with standard 16-pin TSSOP footprints during procurement planning.

Selection Notes

Select this component for designs requiring robust ESD protection and precise timing synchronization in RS-485 networks. It serves as a pin-compatible upgrade to the industry-standard '34C86. Consider the 1nA shutdown current for power-constrained systems requiring periodic bus monitoring.

Part Context

This part belongs to the MAX3093E/MAX3094E family of rugged, low-power quad receivers. While the MAX3094E operates at 3.3V, the MAX3093E variant specifically targets 5V systems. The ECUE+T suffix denotes the commercial temperature grade and surface-mount TSSOP packaging format.

Replacement Considerations

The datasheet identifies the MAX3093E as a direct pin-compatible upgrade to the industry-standard '34C86 receiver.
