The SN65HVD74D is a RS-485 Full-duplex Transceiver for use with encoders and decoders. This device extends the RS-485 portfolio with a family of full-duplex transceiver with robust 3.3V drivers and receivers and high levels of ESD protection. The ESD protection includes >±30kV HBM and >±12kV IEC61000-4-2 contact discharge. The large receiver hysteresis of the SN65HVD7x devices provides immunity to conducted differential noise and the wide operating temperature enables reliability in harsh operating environments. This device each combines a differential driver and a differential receiver, which operate from a single 3.3V power supply. Each driver and receiver has separate input and output pins for full-duplex bus communication designs. This device all features a wide common-mode voltage range which makes the devices suitable for multi-point applications over long cable runs. The device is fully enabled with no external enabling pins.
