SN65HVD1785

illustrate

These devices are meant to survive, such as direct short circuits to power supply overvoltage faults, miswiring faults, connector failures, cable shredding, and improper tooling applications. They are also sound to ESD events, with high levels of protection for human body model specifications.

These devices combine a differential driver and a differential receiver that operate from a single supply. In the 'HVD1785,'HVD1786,' and 'HVD1787,differential output drivers and receivers are connected to form an internal bus port for half-duplex (two-wire bus) communication. In the HVD1793, the differential output driver and receiver differential inputs are independent pins, resulting in a bus port full-duplex (four-wire bus) communication.
