MAX13442EASA+

Drivers, Receivers, Transceivers Overview

The MAX13442EASA+ is a half-duplex RS-485 transceiver in an 8-pin SO package, operating from a +4.75V to +5.25V supply with a maximum data rate of 250kbps. It features ±80V fault protection on the A and B pins, ±15kV ESD protection via Human Body Model, and true fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. The device includes hot-swap circuitry for DE and RE pins, foldback current limiting, and thermal shutdown. It supports up to 128 transceivers on a single bus due to its 1/4-unit-load receiver impedance and operates within a temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• ±80V fault protection withstands signal faults on communication bus lines without damage
• Hot-swap capability prevents false transitions during circuit initialization or connection to a live backplane
• True fail-safe receiver inputs guarantee a logic-high output when inputs are open, shorted, or idle
• Reduced slew-rate driver minimizes electromagnetic interference and reflections for error-free transmission

Drivers, Receivers, Transceivers Applications

• RS-422/RS-485 communications
• Truck and trailer applications
• Industrial networks
• Automotive applications
• HVAC controls

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the 8-pin SO configuration and ensure the suffix indicates lead-free/RoHS compliance. Cross-reference the part number with authorized distributor catalogs to confirm availability status and regional sales restrictions before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this transceiver for systems requiring robust fault protection against high-voltage bus shorts up to ±80V. The reduced slew rate makes it suitable for applications where minimizing EMI and reflections is critical, such as long cable runs or noisy environments. Ensure the system operates within the specified 5V supply range and requires half-duplex communication capabilities.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1344xE family of fault-protected RS-485/J1708 transceivers manufactured by Analog Devices / Maxim Integrated. The family includes variants like the MAX13443E (10Mbps) and MAX13444E (J1708), sharing similar pinouts and protection features but differing in data rates and specific protocol support.
