I need your help.
I have a test at my job comming soon and I might be asked about TTL, CMOS and EIA voltage ranges.
I have been google-ing for 4 days now, but I haven't found anything useful.
I know that the EIA voltages are +15 to +3V for 1 logic and -15 to -3V for 0 logic.
Also I know that for TTL for 0 logic the range is 0 to 0.8V.
PLEASE HELP ME! I know I have studied this in faculty, but I don't have the courses.(they are at my parents' home as I don't have to much storage space here)
PS.:As this is an urgent matter, I will award a lot of points....
