Explanation of the AC Symbols
Each timing symbol has 5 characters. The first character is always a 鈥淭鈥� (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掳C (commercial temperature range); VSS = 0 V; VCC = 5 V 卤 10%; -M and -V ranges.
TA = -40掳C to +85掳C (industrial temperature range); VSS = 0 V; VCC = 5 V 卤 10%; -M and -V
ranges.
TA = 0 to +70掳C (commercial temperature range); VSS = 0 V; 2.7 V < VCC < 5.5 V; -L range.
TA = -40掳C to +85掳C (industrial temperature range); VSS = 0 V; 2.7 V < VCC < 5.5 V; -L range.
Table 14-3. gives the maximum applicable load capacitance for Port 0, Port 1, 2 and 3, and ALE
and PSEN signals. Timings will be guaranteed if these capacitances are respected. Higher
capacitance values can be used, but timings will then be degraded.

Table 8-5., Table 8-8. and Table 8-11. give the description of each AC symbols.
