Overview
The SN65HVD73DGSR is a 3.3V full-duplex RS-485 transceiver manufactured by Texas Instruments. This device is part of the SN65HVD7x family, which extends the RS-485 portfolio with robust 3.3-V drivers and receivers and high levels of ESD protection. It is designed to operate in harsh operating environments, offering a wide operating temperature range from –40°C to 125°C. The transceiver combines a differential driver and a differential receiver, each with separate input and output pins for full-duplex bus communication designs, making it suitable for multi-point applications over long cable runs.
