I am looking to use a pulse output generator from Al Williams with my Butterfly. The problem is that the output generator operates at 5 volts and the Butterfly at 3.3 volts.
I have searched for a thread on this but did not find something that I thought would work. Maxim has a Logic Level Translator chips. Are these a good answer or is there something else that will work.
The pules output chip takes serial data with a ShiftIn and ShiftOut system ( I believe SPI will work) for control and outputs a pulse stream as required.
I have used this before and it works very well, I just forgot about it. For production type projects it is likely too expensive but for my hobby type stuff it is easier, I just need to bridge between 3.3 volts and 5 volts.
