So.... I didn't read the spec sheets thoroughly (or didn't fully take them in)
so now I need to get some logic level shifters... The devices I have are a mixture of 1.8v and 3.3v, I'm using a Boarduino (or a Duemilanove intially) which is of course a 5v device.
These little beasties look perfect for the job: http://uk.farnell.com/analog-devices/adg3301bksz/translator-sgl-ll-bidir-6sc-70/dp/2067851
Bi-directional, work from 1.15 to 5.5v, and available in 4 or 8 channel as well. Except they're SMTs and I'm already going to be suffering enough with SMTs...
There's also these: http://uk.farnell.com/on-semiconductor/mc14504bcpg/ic-4000-cmos-4504-dip16-15v/dp/9665064
DIP, so I can socket them easily, but will they do the job? I've tried reading the data sheet, but whilst it sometimes mentions 3-15v, it also mentions -0.5-15v as input ranges.
Anyone used an MC14504 with a 1.8v chip? Will it work, or do I need to break out the magnifying glass again?
Thanks in advance.
