The NXP PCA9512AD,118 is a single-channel I²C/SMBus buffer and accelerator designed for hot-swap applications — it isolates the bus capacitance of a card being inserted from the live backplane, preventing data corruption during insertion or removal.
ROHS3 compliant per the manufacturer's declaration; no additional REACH or UL certification is documented in the available spec data.
It is an I²C/SMBus buffer and accelerator for hot-swap applications — it allows a card to be inserted into or removed from a live backplane without corrupting the bus data.
