« on: December 28, 2008, 11:18:44 AM »
hello, as I wish to use some rotary encoders for MPGs, those:

http://it.rs-online.com/web/search/searchBrowseAction.html?method=searchProducts&searchTerm=263-2889&x=15&y=10

and I want use port 2 pins 2-9 that are described on manual as CMOS thresholds inputs, I wish to know if it mean have 1 level to 12 volts or 5? If I will use the CD4504 TTL to Mos translator can I assume it will do the work?

Thanks in advance

you should be able to connect this with a 5 volt supply and connect it straight to the breakout board.

Or have a look at these, these work even better
