PCA9543AD
by TI(德州仪器)
When one controller needs to route an I²C bus between downstream branches, the PCA9543AD serves as a bus switch. This Texas Instruments part is in a surface-mount SO-14 package, with 14 symbol pins and 14 matching footprint pads. The free verified KiCad package supplies the symbol, the SO-14_L8.7-W3.9-P1.27-LS6.0-BL footprint, and a 3D model so the device can be checked in board context. A conversion used by 1 ProtoFlow engineer in real designs underpins these files. The component can be opened directly in ProtoFlow for schematic and PCB work.
