#95632 - re: TTL terminology Responding to: ???'s previous message |
Here are some websites to "try" and clear up the terminology issues:
http://www.interfacebus.com/voltage_L...shold.html http://en.wikipedia.org/wiki/Tran...stor_logic It appears that the only issue with LVTTL is whether the IC is designed to handle the output from a standard TTL (5V) chip when it is at a high level. The link that I gave in my earlier post, http://www.quicklogic.com/images/quicknote92.pdf, is an inelegant way of handling this interface. It would be a better solution to use appropriate buffer chips. Jacob |
