Explanation of the AC 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 sta-
tus of that signal. The following is a list of all the characters and what they stand for.
Example:TAVLL = Time for Address Valid to ALE Low.
TLLPL = Time for ALE Low to PSEN Low.
TA = 0 to +70°C (commercial temperature range); VSS = 0 V; VCC = 5 V ± 10%; -M and -V ranges.
TA = -40°C to +85°C (industrial temperature range); VSS = 0 V; VCC = 5 V ± 10%; -M and -V
ranges.
