3 Description

These devices are designed to survive overvoltage faults such as direct shorts to power supplies, mis- wiring faults, connector failures, cable crushes, and tool mis-applications. They are also robust to ESD events, with high levels of protection to human-body model specifications.

These devices combine a differential driver and a differential receiver, which operate from a single power supply. In the 'HVD1785, 'HVD1786, and 'HVD1787, 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. In the 'HVD1793, the driver differential outputs and the receiver differential inputs are separate pins, to form a bus port suitable for full- duplex (four-wire bus) communication. These ports feature a wide common-mode voltage range, making the devices suitable for multipoint applications over long cable runs. These devices are characterized from –40°C to 105°C.

For similar features with 3.3-V supply operation, see the SN65HVD1781 (SLLS877).
