MAX3093EESE+T

Overview

The MAX3093EESE+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 the Human Body Model, ±8kV IEC 1000-4-2 Contact Discharge, and ±15kV Air-Gap Discharge. Propagation delays are guaranteed within ±8ns tolerance. It includes a low-power shutdown mode with 1nA typical supply current and a fail-safe feature ensuring a logic-high output when inputs are open circuit. The input impedance allows up to 128 receivers on a bus. It is housed in a 16-pin Narrow SO package.

Feature Summary

• Integrated ±15kV ESD protection for harsh environments
• Guaranteed propagation-delay matching between devices
• Low-power shutdown mode with high-impedance outputs
• Fail-safe design ensures 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 against official documentation to confirm the package type and temperature range. Confirm that the component meets RoHS compliance requirements for your assembly process. Ensure the datasheet revision matches the technical specifications required for your design implementation.

Selection Notes

Select this component for designs requiring robust ESD protection and precise timing matching across multiple receivers. Verify that the system operates within the specified +5V supply voltage range. Consider the narrow SO package dimensions if board space is constrained. Ensure the application benefits from the quarter-unit-load input impedance for high node counts.

Part Context

This part belongs to the MAX3093E/MAX3094E family of low-power, rugged quad receivers. It serves as a pin-compatible, low-power upgrade to the industry-standard '34C86. While the MAX3094E variant operates at 3.3V, this specific model is optimized for 5V systems. It shares functional similarities with other Maxim interface ICs but is distinct in its specific ESD ratings and delay tolerances.

Replacement Considerations

The MAX3093E is a direct pin-compatible replacement for the '34C86. When substituting, verify that the new component's ESD protection levels meet or exceed the original design requirements. Ensure the operating voltage and data rate specifications remain compatible with the existing bus architecture.
