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. The internal current-limit circuits allow fault survivability without causing the high bus currents that otherwise might damage external components or power supplies. They are also robust to ESD events, with high levels of protection to the JEDEC or IEC human-body-model specification.

These devices combine a differential driver and a differential receiver, which operate from a single power supply. 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.
