TCA6416A: TCA6416 vs TCA6416A Improvements

Part Number: TCA6416A
Other Parts Discussed in Thread: TCA6416


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.
