You are...
When you use 2 - 3V targets, supply voltage for 74HC126 just 2 - 3V. Inputs of 74HC have protection diods to supply (2-3V). That's why you can't set 5V (RA5, RA2,RC5, RC3) directly to U6 (as 74HC126).
No, I can't. Your schematic needs 74AHC126 and 74VHC126 and so on...
jenda said:What do you mean with "permanently"? Always in high state or what?
If your schematic is for 5v targets only, why you hadn't eliminated level shifters (U6 and U9)?jenda said:As mentioned obove: as long as everything is running at 5V you will have no problems with HC/T.
jenda said:Testu, if you chech the BOM you'll find the correct parts.
I've download the schematic of icd2 from the website,but I do't understand it very well.There are many question for me.h**p://www.mcu.cz/modules/news/article.php?storyid=449 - now with english description

I think it should be file from 24C EEPROM where is stored the program for an USB chip.
OOPS, this is only configuration (VID, PID, etc). USB chip is preprogramed from Cypress or programed from driver via USB
