Overview
The SN65HVD35D is a 3-state differential line driver and differential-input line receiver designed by Texas Instruments. This component operates with a 3.3-V power supply and is specifically tailored for RS-422 and RS-485 data transmission. It supports full-duplex bus communication, enabling separate input and output pins for efficient data transfer. The device is characterized for ambient temperatures ranging from –40°C to 85°C and can operate at temperatures up to 105°C or 125°C, depending on the package option.
