Overview
The PCA9510AD,118 is a hot swappable I²C-bus and SMBus buffer produced by NXP USA Inc. This component is designed to facilitate the insertion of I/O cards into a live backplane without corrupting the data and clock buses. It ensures smooth operation by isolating the backplane and card capacitances, thereby preventing bus contention and data corruption during hot swapping.
