Hot swappable I
2
C-bus and SMBus bus buffer
See Application Note AN10160, ‘Hot Swap Bus Buffer’ for more information on
applications and technical assistance.
Remark: The PCA9510A can be used in any combination depending on the number of rise time accelerators that are needed
by the system. Normally only one PCA9510A would be required per bus.
