SN65HVD72DRBT Description

Short technical summary and product information.

The SN65HVD72DRBT is a half-duplex RS-485 transceiver from Texas Instruments, operating on a 3.3V supply. It is designed for reliable data transmission in industrial environments, featuring IEC ESD protection up to ±12kV contact discharge.

 

This transceiver supports RS-422 and RS-485 protocols with a maximum signaling rate of 250kbps. It includes one driver and one receiver, with a wide common-mode voltage range of -7V to 12V and receiver hysteresis of 80mV for enhanced noise immunity. The device operates across an extended industrial temperature range from -40°C to 125°C.

 

Available in an 8-SON (3x3) package, the SN65HVD72DRBT is suitable for surface mount applications. Its design prioritizes low power consumption, with a maximum supply current of 950µA during operation. The fault protection voltage ranges from -13V to 16.5V, ensuring durability in demanding conditions. It supports up to 200 nodes on the bus.
