MAX3483EESA+

Overview

The MAX3483EESA+ is a half-duplex RS-485/RS-422 transceiver in an 8-pin SO package. It operates from a single +3.0V to +3.6V supply with typical current of 1.1mA and shutdown current of 2nA. The device supports data rates up to 250kbps with slew-rate-limited drivers. ESD protection reaches ±15kV (HBM) and ±8kV (IEC Contact). It features thermal shutdown, short-circuit current limiting, and a fail-safe receiver.

Feature Summary

• Slew-rate-limited driver minimizes electromagnetic interference and reflections
• Enhanced electrostatic discharge protection on all I/O pins
• Low-power shutdown mode for significant energy savings
• Fail-safe receiver guarantees logic-high output when inputs are open

Applications

• Telecommunications systems
• Industrial-control local area networks
• EMI-sensitive applications
• Integrated services digital networks
• Packet switching environments

Procurement Notes

Verify the ordering suffix 'ES' confirms the extended temperature range of -40°C to +85°C and the 'SA' indicates the 8-pin SO package. Confirm RoHS compliance status via the manufacturer's official documentation before finalizing procurement specifications.

Selection Notes

Select this component for half-duplex RS-485 or RS-422 communication requiring low power consumption and high ESD immunity. Ensure the application does not require full-duplex operation, as this model lacks separate transmit and receive differential pairs.

Part Context

This part belongs to the MAX3483E family of 3.3V-powered transceivers. It shares the industry-standard 75176 pinout with other variants like the MAX3485E and MAX3486E, facilitating design reuse across different speed requirements within the same product line.

Replacement Considerations

MAX3483EESA is the non-RoHS equivalent. ADM3483ARZ is a similar Analog Devices alternative.
