MAX13444EASA/V+T

Drivers, Receivers, Transceivers Overview

The MAX13444EASA/V+T is an automotive-qualified, fault-protected RS-485 and J1708 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +4.75V to +5.25V supply within the -40°C to +125°C temperature range. The device features ±80V fault protection on the A and B pins, ±15kV ESD protection, and true fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. It supports up to 128 transceivers on a bus via its 1/4-unit-load input impedance. The driver utilizes enhanced slew-rate limiting for error-free transmission up to 250kbps with reduced EMI. Hot-swap circuitry prevents false transitions during live backplane connection.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced slew-rate limiting minimizes electromagnetic interference (EMI) and reflections for reliable data transmission.
• Robust ±80V fault protection withstands signal faults on communication bus lines without damage.
• Hot-swap capability eliminates false transitions during circuit initialization or connection to a live backplane.
• True fail-safe receiver inputs ensure a logic-high output state when inputs are open, shorted, or idle.

Drivers, Receivers, Transceivers Applications

• J1708 compliant automotive networks
• Truck and trailer applications
• Industrial networks requiring high fault tolerance

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffixes against official documentation to confirm package type and tape-and-reel configuration. Ensure the component meets the required automotive qualification standards indicated by the '/V' designation. Cross-reference the manufacturer's ordering information to validate availability and compliance with current environmental directives.

Drivers, Receivers, Transceivers Selection Notes

Select this component for systems requiring J1708 protocol support alongside standard RS-485 compatibility. The ±80V fault protection distinguishes it from lower-rated alternatives like the MAX13443E. Consider the 250kbps maximum data rate constraint due to slew-rate limiting when designing high-speed communication links.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1344xE family of fault-protected transceivers. It shares the same pinout and core architecture as the MAX13442E and MAX13443E but is specifically optimized for J1708 applications with enhanced fault tolerance. The '/V' suffix denotes automotive qualification, while '+T' indicates a tape-and-reel packaging format.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13442EASA+T is a functional substitute for general RS-485 applications but lacks J1708-specific TXD control. The MAX13443E offers higher speed but provides only ±60V fault protection. Verify thermal dissipation requirements when substituting devices with different power consumption profiles.
