Hi, all:
My PMC card is only 3.3V IO environment, and the PCI is 5V IO
environment(PC), I want to debug my PMC card in PCI, so I have to design a
adapter from PCI(5V environment) to PMC(3.3V environment).
1. Which chip can be used in this case? and have any successful application?
2.I use TI SN74CBTD3861 as PCI buffer and voltage shifting in my adapter,
but it doesn't work at all, why?
Thank you in advance!
