The SN65HVD78D is a 3.3V robust Half-duplex Driver and Receiver. The bus pins are robust to ESD events with high levels of protection to human-body model and IEC contact discharge specifications. Each of these devices combines a differential driver and a differential receiver which operate from a single 3.3V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. This device features a wide common-mode voltage range making the devices suitable for multi-point applications over long cable runs.
