MAX3488ESA+T

Overview

The MAX3488ESA+T is a low-power, full-duplex transceiver designed for RS-485 and RS-422 communication applications. It operates from a single +3.0V to +3.6V supply voltage without requiring a charge pump. The device integrates one driver and one receiver within an 8-pin SOIC package. It supports data transmission rates up to 250kbps with slew-rate-limited drivers to minimize electromagnetic interference (EMI). The unit functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Full-duplex communication capability with independent driver and receiver paths
• Slew-rate limited drivers reduce EMI and reflections on improperly terminated cables
• Operates from a single +3.3V supply without the need for charge pumps
• Driver outputs feature short-circuit current limiting and thermal shutdown protection

Applications

• Industrial control local area networks
• Telecommunications systems
• Transceivers for EMI-sensitive applications

Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official documentation. Confirm the specific suffix indicates the RoHS-compliant status and tape-and-reel packaging format. Ensure the ordering information matches the required temperature grade and package type for your specific design implementation.

Selection Notes

Select this component when full-duplex operation is required alongside low electromagnetic interference. The slew-rate limitation makes it suitable for long cable runs or noisy environments where signal integrity is critical. It serves as a direct alternative to half-duplex variants like the MAX3483 when simultaneous bidirectional communication is necessary.

Part Context

This part belongs to the MAX348x family of 3.3V-powered transceivers manufactured by Analog Devices/Maxim Integrated. It shares the industry-standard pinout with other devices in the series but differs in duplex mode and speed capabilities. The 'E' designation specifies the extended industrial temperature range, while the '+T' suffix denotes the RoHS-compliant reel packaging.

Replacement Considerations

The MAX3490EESA+T provides similar functionality but supports higher data rates up to 10Mbps. For half-duplex applications requiring lower power consumption, the MAX3483ESA+T is a compatible alternative.
