AC Characteristics
EXPLANATION OF THE AC SYMBOLS
Each timing symbol has three or five characters. The
first character is always ‘‘T’’ (for time). The other
characters, depending on their positions, stand for
the name of a signal or the logical status of that
signal. Table 3 lists the characters and their mean-
ings.
Example
TAVLL
e
Time for Address Valid to ALE Low.
TLLPL
e
Time for ALE Low to PSEN Low.
