MAX13487EESA+T | RS-485/RS-422 Transceiver
The MAX13487EESA+T is a robust 3.3V RS-485/RS-422 transceiver designed for high-speed communication in noise-prone environments. It supports data rates up to 25Mbps and operates across an extended temperature range of -40°C to +85°C. The device integrates fail-safe circuitry to ensure a logic-high output when inputs are open or shorted, making it ideal for industrial and automotive applications. With its compact 8-pin SOIC package, it balances performance and space efficiency for modern embedded systems.
Key Features
The MAX13487EESA+T excels in low-power operation, consuming only 300µA of supply current during active transmission and 1µA in shutdown mode. It features ±16kV ESD protection on bus pins (IEC 61000-4-2), enhancing reliability in harsh electrical environments. The transceiver supports full-duplex communication with a 1/8-unit load, allowing up to 256 nodes on a single bus. Its slew-rate-limited outputs minimize EMI, while hot-swap capability prevents damage during live insertion. Additionally, the device includes thermal shutdown and short-circuit current limiting for fault-tolerant operation.
Applications
This transceiver is widely used in industrial automation networks (e.g., PROFIBUS, MODBUS), building control systems, and smart grid infrastructure. It enables reliable long-distance communication in motor control units, HVAC systems, and smart meters. The device is also suitable for automotive diagnostic interfaces and renewable energy monitoring systems where EMI immunity and low power consumption are critical. Its compatibility with 3.3V microcontrollers simplifies designs for IoT edge devices and battery-powered equipment.
1. SN65HVD72DR (Texas Instruments): A 3.3V RS-485 transceiver with 25Mbps speed and ±16kV ESD, optimized for multipoint networks. Lacks integrated fail-safe but offers lower quiescent current (120µA).
2. ADM3490ARZ (Analog Devices): Supports 12Mbps with ±15kV ESD protection, featuring a reduced slew rate for lower EMI. Suitable for moderate-speed industrial networks.
3. LTC2862ACS8#PBF (Analog Devices): A 20Mbps transceiver with ±60V overvoltage fault protection, ideal for harsh industrial environments. Operates from 3V to 5.5V supplies.
4. SP3485EN-L/TR (Exar): Cost-effective 10Mbps RS-485 transceiver with 32-node capacity and 1µA shutdown current, suited for budget-sensitive projects.
Selection Note
For applications requiring 3.3V operation and high-speed performance, the MAX13487EESA+T outperforms alternatives like the SP3485EN in both speed and ESD robustness. However, the LTC2862ACS8#PBF may be preferable for extreme overvoltage conditions, while the SN65HVD72DR offers lower power consumption for battery-dependent systems. Designers should prioritize ESD ratings, node count, and supply voltage compatibility when selecting replacements.
