Description for the SN65HVD78

These devices have robust 3.3-V drivers and receivers in a small package for demandingindustrial applications. The bus pins are robust to ESD events with high levels of protection toHuman-Body Model and IEC Contact Discharge specifications.

Each of these devices combines a differential driver and a differential receiver whichoperate from a single 3.3-V power supply. The driver differential outputs and the receiverdifferential inputs are connected internally to form a bus port suitable for half-duplex (two-wirebus) communication. These devices feature a wide common-mode voltage range making the devicessuitable for multi-point applications over long cable runs. These devices are characterized from–40°C to 125°C.
