Product Overview: SN65HVD1471DGK

The SN65HVD1471DGK is a robust, high-performance transceiver module from Texas Instruments, designed to facilitate communication on RS-485 and RS-422 networks. This device is particularly well-suited for industrial applications where long-distance data transmission is required, along with a high degree of noise immunity and reliability.

Encapsulated in an 8-pin MSOP (DGK) package, the SN65HVD1471 is engineered to operate over a wide temperature range of -40°C to 125°C, ensuring its functionality in extreme environments. Its versatility is further enhanced by a wide supply voltage range of 3.3V to 5V, making it compatible with a variety of systems and power configurations.

Key Features

• Bus-Pin ESD Protection: The SN65HVD1471 comes with an impressive Electrostatic Discharge (ESD) protection for the bus-pin, exceeding 16 kV HBM (Human Body Model), which provides robustness against static electricity and other forms of ESD.
• Signaling Rate: Capable of achieving signaling rates up to 50 Mbps, this transceiver is designed for high-speed data transmission, ensuring efficient communication across networks.
• Low Power Consumption: With a low standby current of 1 µA max, the SN65HVD1471 is optimized for power-sensitive applications, reducing the overall energy consumption of the system it is integrated with.
• Thermal Shutdown Protection: The device includes a thermal shutdown feature that prevents damage from overheating, contributing to the longevity and durability of the module.
• Differential Output: The differential output exceeds the RS-485 requirements, providing a robust signal for reliable data transmission even in electrically noisy environments.
• Fail-Safe Receiver: The fail-safe receiver ensures a logic-high output when the inputs are open, shorted, or idle, enhancing data integrity and network stability.
