The SN65HVD1473DGSR is a robust 3.3V differential bus transceiver designed by Texas Instruments to facilitate communication over RS-485 and RS-422 networks. This particular model comes in a compact surface-mount package, specifically a SOIC-8 (DGSR) package, making it well-suited for space-constrained applications that require high-speed data transmission and noise immunity.

Key Features

• Bus-Pin ESD Protection: With an impressive Electrostatic Discharge (ESD) protection level of up to 15kV on the bus pins, the SN65HVD1473DGSR ensures reliability and durability in harsh electrical environments.
• Wide Common-Mode Range: The device is capable of handling common-mode voltages from -7V to +12V, making it versatile for various bus conditions and enhancing fault tolerance.
• Thermal Shutdown Protection: The inclusion of thermal shutdown protection prevents damage to the device from excessive power dissipation and high temperatures.
• Low Power Consumption: It operates with a very low quiescent power consumption, which is less than 1mA, optimizing energy efficiency for the system.
• High Data Rate: The transceiver supports data rates up to 3 Mbps, enabling fast data transmission for time-sensitive applications.
• Failsafe Receiver: The failsafe receiver ensures a logic-high output when the bus is open, shorted, or idle, thus maintaining signal integrity.

Applications

The SN65HVD1473DGSR is suited for a range of industrial applications including factory automation, building automation, and process control systems. It is also ideal for applications requiring high-speed data communications such as HVAC systems, telecom infrastructure, and networking equipment.
