Full-duplex transceivers with robust 3.3V drivers and receivers

Expanding its RS-485 portfolio, Texas Instruments (TI) has introduced a new family of full-duplex transceivers 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. The SN65HVD7x devices are offered in a standard SOIC package as well as in a small-footprint MSOP package. The devices each combine 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. The devices feature a wide common-mode voltage range which makes the devices suitable for multi-point applications over long cable runs.
