EXPLANATION OF THE AC SYMBOLS
In defining the clock waveform, care must be taken not to exceed
the MIN or MAX limits of the AC electrical characteristics table.
Each timing symbol has five characters. The first character is always
‘t’ (= time). The other characters, depending on their positions,
indicate the name of a signal or the logical status of that signal. The
designations are:
C – Clock
D – Input data
H – Logic level high
L – Logic level low
Q – Output data
T – Time
V – Valid
X – No longer a valid logic level
Z – Float
V_CC –0.5
0.45V
0.2 V_CC + 0.9
0.2 V_CC – 0.1
