SN65HVD485EDR

The SN65HVD485EDR is a robust, half-duplex RS-485 transceiver designed for reliable data communication over long distances, commonly used in industrial and commercial applications. It operates on a 5V power supply and supports data rates up to 10 Mbps. This device is part of Texas Instruments' family of RS-485 transceivers, known for their high ESD protection and wide common-mode voltage range, making them suitable for harsh environments.
Key features include a low standby current of 1 µA, thermal shutdown protection, and an extended operating temperature range of -40°C to 85°C. The transceiver supports up to 256 nodes on a single bus, thanks to its 1/8 unit load design, which reduces the loading effect on the network.
It also provides fail-safe receiver inputs to ensure a known output state when the bus is idle, open, or shorted. With its compact SOIC-8 package, the SN65HVD485EDR is ideal for applications that require space-efficient solutions without compromising performance.
