The MAX3443EASA+ from Analog Devices (Maxim Integrated) is a fault-protected RS-485 transceiver designed for robust communication in demanding environments. It offers ±60V fault protection on bus lines and ±15kV ESD protection, minimizing the need for external components. This transceiver supports data rates up to 10Mbps and operates from a 4.75V to 5.25V supply.
Key features include true fail-safe receiver inputs, ensuring a logic-high output when the bus is open or idle, and hot-swappable circuitry to prevent false transitions during initialization. The 1/4-unit-load receiver input impedance allows up to 128 transceivers on a single bus, making it suitable for large network configurations.
This device is housed in an 8-pin SOIC package, designed for surface mounting. It operates across an industrial temperature range of -40°C to 125°C, making it suitable for applications such as industrial networks, telecommunications systems, and HVAC controls.
The MAX3443EASA+ is specified for RS-422 and RS-485 communication protocols. Its enhanced slew-rate limiting facilitates error-free data transmission, and it includes short-circuit current-limiting and thermal shutdown for driver protection.
