TABLE 14-7: AC Electrical Characteristics (Continued) (2 of 2)
Explanation of Symbols Each timing symbol has 5 characters. The first character is always a ‘T’ (stands for
time). The other characters, depending on their positions, stand for the name of a signal or the logical status of that
signal. The following is a list of all the characters and what they stand for.
