Overview
The SN65HVD75DGKR is a 3.3-V supply, half-duplex RS-485 transceiver produced by Texas Instruments. This device is part of the SN65HVD7x family, which is designed for demanding industrial applications. It combines a differential driver and a differential receiver in a small package, making it suitable for space-constrained designs. The transceiver operates from a single 3.3-V power supply and features robust ESD protection and a wide common-mode voltage range, making it ideal for multi-point applications over long cable runs. The device is characterized over an extended industrial temperature range of –40°C to 125°C.
