MAX3093ECUE

Overview

The MAX3093ECUE 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 on all inputs, ensuring reliability in harsh environments. It includes a low-power shutdown mode with typical current consumption of 1nA. The propagation delay is guaranteed within ±8ns tolerance for precise timing matching. Operating temperature range is specified from 0°C to +70°C. The component is housed in a 16-pin TSSOP package.

Feature Summary

• Provides robust electrostatic discharge protection meeting IEC 1000-4-2 standards for air-gap and contact discharge scenarios.
• Features a low-power shutdown mode that reduces supply current to approximately 1nA when enabled inputs are deactivated.
• Incorporates fail-safe circuitry that guarantees a logic-high output state if the differential input terminals remain open-circuited.

Applications

• Telecommunications equipment requiring reliable serial communication interfaces
• Rugged RS-422/RS-485 bus receiver networks operating in electrically noisy environments
• Level translation circuits connecting different voltage domains in industrial systems

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) rather than the extended range ('E'). Confirm the 'U' suffix corresponds to the TSSOP package variant. Ensure the datasheet revision matches the required specifications for your design implementation.

Selection Notes

Select this component when a 5V supply is available and high-speed data reception is required. Consider the MAX3094E variant if a 3.3V supply system is utilized instead. Evaluate the need for the low-power shutdown feature against active power consumption requirements in the final application design.

Part Context

This receiver belongs to the MAX3093E/MAX3094E family designed as pin-compatible upgrades to the industry-standard '34C86 devices. The series offers improved power efficiency and enhanced ESD protection capabilities compared to legacy components while maintaining functional compatibility.

Replacement Considerations

The MAX3093ECSE serves as an alternative package option using the narrow SOIC format. The MAX3093ECPE provides a plastic DIP package variant for through-hole mounting applications requiring similar electrical characteristics.
