I don't know how to thank you all but maybe this will help someone like me. Anyway I m not an engineer and just don't have time to think much on other things because I have very complex project in front of me regarding FPGA devices. So I calculated that 700 ohm resistor should be fine and used...
Re: Overvoltage protection
That is not solution because if I add resistor value to drop voltage for 7V (from 12V to 5V) I would end up with problems when I test 5V because that voltage would be also dropped. So I need something like relay who will activate for anything higher then 5V and block...
I have created Logic Analyzer board using FPGA and ALVC devices(voltage level translators) for investigating CMOS signals and I come across one problem regarding over voltage protection. Logic Analyzer is working perfect but sometimes I "touch" 12V power sources in process of gathering signals...
There is something wrong with quickswich devices. As I know MC68000 cant
support 3.3V (some versions can but mine just cant). When i use quickswich
any type i only get 5V to 3.3V translation and no vice versa. I need to use
dual voltage level translator with auto sensing. Only parts that I can...
It is easy to create PLCC68 Socket, but this one is not standard one. It has Through Hole Vertical Termination and it needs to be mounted at the bottom side of pcb. I have no idea how to create this socket. I was thinking about creating footprint just with holes. Here is some info about socket...
Hi all, my idea is to use Cyclone II to replace Mc68000 on Amiga board, but there is some problems. Cyclone dont have 5V tolerance so i need to solve that. I read on this forum about level shifters, quickswiches with zero delay, and buffer transceivers.
I read about quickswich QS3861, and level...
