MAX13444EASA+

Drivers, Receivers, Transceivers Overview

The MAX13444EASA+ is a half-duplex RS-485/J1708 transceiver in an 8-pin SO package. 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, and true fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. It includes hot-swap circuitry on the RE pin to prevent false transitions during bus connection. The receiver input impedance is 1/4-unit-load, allowing up to 128 transceivers on a single bus. Operating temperature range is -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced slew-rate limiting minimizes electromagnetic interference and reflections for error-free transmission at lower data rates.
• Robust fault protection withstands signal line faults up to ±80V without damage, eliminating the need for external protection components.
• Integrated hot-swap circuitry on the receiver enable pin prevents data bus disturbances during board insertion into live backplanes.
• True fail-safe receiver inputs ensure a defined high logic state when differential inputs are open, shorted, or idle.

Drivers, Receivers, Transceivers Applications

• J1708 automotive communication networks
• RS-485 industrial control systems
• Truck and trailer telematics applications
• HVAC control systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure the component matches the required J1708 or RS-485 protocol specifications for your design. Cross-reference the datasheet revision date to confirm all electrical characteristics align with your system requirements before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing for harsh automotive or industrial environments requiring high fault tolerance. The MAX13444EASA+ is suitable for applications needing J1708 compliance or robust RS-485 connectivity with reduced EMI. Consider the 250kbps maximum data rate and the specific hot-swap functionality available only on the RE pin for this variant compared to other family members.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX1344xE family of fault-protected transceivers manufactured by Analog Devices / Maxim Integrated. It shares the same 8-pin SO package and core architecture as the MAX13442E and MAX13443E. The primary distinction lies in its optimized driver characteristics for J1708 standards and specific hot-swap implementation on the RE pin, differentiating it from the standard RS-485 focused variants.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13442EASA+ is a functional substitute within the same family, offering identical fault protection and data rates but potentially differing in hot-swap pin configuration. Verify pin compatibility and specific J1708 timing requirements when substituting. Other MAX1344x variants may offer higher speeds or different shutdown behaviors.
