Description

The SN65HVD1792 is designed to survive overvoltage faults such as direct shorts to power supplies, mis-wiring faults, connector failures, cable crushes, and tool mis-applications. It is also robust to ESD events, with high levels of protection to human-body model specifications.

The SN65HVD1792 combines a differential driver and a differential receiver, which operate from a single power supply. The SN65HVD1792 is characterized from –40°C to 105°C.
