    Hi,

    We have a handful of devices that are pin to pin with the PCA9508. For example TCA9517,TCA9617, TCA980x family. The problem is these devices are not hot swappable. If you don't care about hot swappability than the TCA9517 is what I would recommend. It has the same voltage range and the same max frequency. It also has the same static voltage offset but if you want the an identical device with a lower static voltage offset then the TCA9517A is the way to go.

    If you need a hot swappable device then we don't have anything that is p2p.The only hot swappable devices we have are the TCA9511 and the TCA4307.

    Best,

    Chris
