MAX3443ECSA+T

Overview

The MAX3443ECSA+T is a half-duplex RS-485 transceiver in an 8-pin SO package. It supports data rates up to 10Mbps with a supply voltage range of 4.75V to 5.25V and operates from -40°C to +125°C. The device features ±15kV ESD protection, ±60V fault protection on A/B pins, and true fail-safe inputs that guarantee a logic-high receiver output when inputs are open or shorted. It includes hot-swap circuitry for telecom applications and allows up to 128 transceivers on the bus.

Feature Summary

• ±60V Fault Protection
• True Fail-Safe Receiver Inputs
• Hot Swappable for Telecom Applications

Applications

• RS-422/RS-485 Communications
• Industrial Networks
• Telecommunications Systems

Procurement Notes

Verify the component against official Analog Devices documentation to confirm pinout compatibility and electrical specifications. Ensure the ordering suffix matches the required temperature range and packaging format. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Selection Notes

Select this model for high-speed RS-485 networks requiring robust fault tolerance. The 10Mbps rate suits demanding industrial protocols. Verify that the automotive temperature range (-40°C to +125°C) meets environmental requirements. Confirm that the single driver/receiver configuration aligns with system topology needs.

Part Context

This component belongs to the MAX3440E–MAX3444E family of fault-protected transceivers. The 'C' in the part number indicates the commercial-grade SOIC package variant, while the '+T' suffix denotes tape-and-reel packaging. It shares core architecture with other members like the MAX3441E but differs in specific control pin configurations and slew-rate limiting characteristics.
