Overview

The SN65HVD72DR is a 3.3V low-power RS-485 transceiver designed for balanced data transmission in noisy environments. It features a robust half-duplex architecture capable of data rates up to 250 kbps while maintaining high ESD protection for industrial reliability.

Why Choose This Part

This transceiver operates from a single 3.3V supply, reducing system power rails compared to older 5V RS-485 parts. It includes integrated HBM ESD protection up to 12 kV and a wide common-mode voltage range, ensuring stable communication across ground potential differences.

Applications

Industrial Automation
Ideal for connecting PLCs, sensors, and actuators in factory environments using the RS-485 or RS-422 protocols.
Utility Meters
Used in smart meters and grid infrastructure for long-distance data collection where low power consumption is critical.
Building Automation
Facilitates communication between HVAC controllers, lighting systems, and security panels over twisted-pair cabling.

Getting Started

When designing a PCB, place a 0.1 uF decoupling capacitor close to the VCC pin and ensure proper 120-ohm termination resistors are used at the physical ends of the bus. Evaluation can be performed using generic SOIC-8 breakout boards or the TI SN65HVD7x evaluation modules.
