MAX3093EESE

Overview

The MAX3093EESE+ 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 unit utilizes a 16-pin Narrow SO package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated ±15kV electrostatic discharge protection on all receiver inputs for robust operation in harsh environments.
• Guaranteed propagation-delay matching between devices to minimize signal skew across multiple data lines.
• Quarter-unit-load input impedance allows connection of up to 128 receivers on a single bus.
• Fail-safe feature ensures a logic-high output when receiver inputs are left 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 'E' confirms the extended temperature range (-40°C to +85°C) and 'SE' denotes the narrow SOIC package. Confirm the '+' suffix indicates lead-free compliance. Cross-reference the manufacturer part number with official distributor catalogs to ensure authenticity and correct revision status before procurement.

Selection Notes

Select this component when a +5V powered quad receiver is required for RS-422 or RS-485 networks. It serves as a pin-compatible upgrade to the industry-standard '34C86. Ensure the system voltage matches the +5V requirement, as the MAX3094E variant is designed for +3.3V supplies. Verify that the 10Mbps data rate meets the application's bandwidth needs.

Part Context

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

Replacement Considerations

The MAX3093EESE+ is a direct pin-compatible replacement for the industry-standard SN75176 or MC3486 variants. For +3.3V applications, the MAX3094EESE+ offers equivalent functionality with adjusted voltage specifications.
