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 bine a differential driver and a differential receiver, which operate from a single power supply. The driver differential outputs and the receiver differential...
