MAX13442EASA+T

Drivers, Receivers, Transceivers Overview

The MAX13442EASA+T is a half-duplex RS-485 transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply (4.75V to 5.25V) and supports data rates up to 250kbps with enhanced slew-rate limiting. The device features ±80V fault protection on the A and B pins, ±15kV ESD protection via Human Body Model, and true fail-safe receiver inputs. It includes hot-swap circuitry for telecom applications and foldback current limiting. Packaged in an 8-pin SOIC, it functions within an automotive temperature range of -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• ±80V fault protection on signal lines eliminates need for external protection devices
• Hot-swap capability prevents false transitions during board insertion or power-up
• True fail-safe receiver guarantees logic-high output when inputs are open or shorted
• Enhanced slew-rate limiting minimizes EMI and reflections for error-free transmission

Drivers, Receivers, Transceivers Applications

• RS-422/RS-485 communications networks
• Truck and trailer telematics systems
• Industrial network interfaces
• Telecommunications systems requiring hot-swappable modules
• Automotive applications and HVAC controls

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific suffix '+T' indicates tape-and-reel packaging and ensure the 'E' designation matches the required automotive temperature grade (-40°C to +125°C). Cross-reference the datasheet revision to confirm pinout compatibility before integration into existing designs.

Drivers, Receivers, Transceivers Selection Notes

Select this model when ±80V bus fault tolerance is required, distinguishing it from the MAX13443E which offers only ±60V protection but higher speed. Choose this variant over the MAX13444E if J1708 protocol support is not needed. Ensure the design accommodates the 250kbps maximum data rate and utilizes the 8-pin SO package constraints for PCB layout.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1344x family of fault-protected transceivers designed for harsh electrical environments. It shares the same 8-pin SO package and basic interface functionality as the MAX13443E and MAX13444E, differing primarily in fault voltage ratings and protocol support. The family addresses industrial needs for robust communication without external protection components.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13443EASA+T serves as a high-speed alternative with ±60V fault protection. The MAX13444EASA+T provides J1708 protocol support with ±80V protection. Verify that any substitute maintains the ±80V rating and 250kbps performance if those parameters are critical to the application.
