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
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.
