Does Altera Max V CPLD provides isolation when it is powered off?
Because we have IOs connected to a different voltage domain (say 3.3V_Ext) and CPLD is powered by different voltage domain (3.3V_Int). 3.3V_ext will be powered first, so we wanted to ensure that there is no back voltage on CPLD when it is not powered ON yet.

Hello Seshu,
Hope you are doing well. Max V CPLD do not provide isolation when it is turned off. You can refer to more information about your device from this link: https://www.intel.cn/content/dam/www/programmable/us/en/pdfs/literature/hb/max-v/max5_handbook.pdf
Thank you.
