On a supplier website I see the 74HC595 shift register listed with two prefixes: CD and SN. What is the difference and/or what does each one mean. (i.e. SN74HC595, CD74HC595)
Couldn't find anything in the device datasheet.
Thanks...
The difference is hard to find. The only notable difference I could find was operating temperature. You're probably safe going with the cheaper or more readily available version.
