Re: Thanks for the Verilog help

Hi,

5v tolerant..

you also have:

his brother:

and even his bigger brother :)
http://shop.trenz-electronic.de/catalog/product_info.php?products_id=630

I'm using several, the problem is rather mechanical :)
a little too high  but it is possible to buy it without the connectors 
mounted
and only install what is necessary.

EasyFlash3 uses the same IC, and no level shifters, and works fine (well, except for one revision of the 64 mobo that drives RESET via a 555 without a current limiting resistor, meaning drivng reset from the expansion port requires a switch or something that can overpower the 555, but that's not a 3V3 IC's issue).
