TCA6416A: TCA6416 vs TCA6416A Improvements

Part Number: TCA6416A
Other Parts Discussed in Thread: TCA6416

Hello,

I need a little help determine exactly what's changed between the TCA6416 and the TCA6416A.   I understand that there have been improvements regarding the interrupts and the reset line.    Specifically in the TCA6416 (non A) datasheet I see the following:

Are there any other changes to the device other than those listed in the TCA6416 errata sections contained within the datasheet?

    Hi Don,

    The errata section calls out most of the differences in the two devices (where A version has fixes to the non A's errata). There is also a difference in the power supply recommendations table of the datasheet where the non A version is more strict about ramp up and ramp down rates.
