MAX3488ECSA+T

Overview

The MAX3488ECSA+T is a true RS-422/RS-485 transceiver from the MAX3483E family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +3.0V to +3.6V supply and supports full-duplex communication at data rates up to 250kbps. The device features slew-rate-limited drivers to minimize EMI and reflections. It includes ±15kV ESD protection (Human Body Model) and ±6kV IEC 1000-4-2 Contact Discharge protection. Operating temperature ranges from 0°C to +70°C. It is housed in an 8-pin SO package.

Feature Summary

• Full-duplex communication capability with independent driver and receiver channels
• Slew-rate-limited drivers designed to reduce electromagnetic interference and signal reflections
• Enhanced electrostatic discharge protection on all I/O pins for robust operation
• Operates directly from a single +3.3V supply without requiring charge pumps

Applications

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

Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C. Confirm the '+T' designation corresponds to tape-and-reel packaging as per the manufacturer's ordering information. Cross-reference the exact part number with official distributor catalogs to ensure compatibility with current production status and RoHS compliance requirements.

Selection Notes

Select this component when full-duplex RS-422 or RS-485 communication is required within a commercial temperature environment. The slew-rate limitation makes it suitable for applications sensitive to electromagnetic interference or utilizing improperly terminated cables. Ensure the system voltage aligns with the specified 3.0V to 3.6V operating range.

Part Context

This device belongs to the MAX3483E family of low-power transceivers. Unlike half-duplex variants such as the MAX3483E, the MAX3488E provides simultaneous transmission and reception. It shares common interface standards and protection features with other members of the series but is distinct in its duplex mode and lack of shutdown control pins.

Replacement Considerations

MAX3490ESA+T offers similar full-duplex functionality but supports higher data rates up to 12Mbps without slew-rate limiting.
