Notes:
8. Part (a) of AC Test Loads and Waveforms used for all parameters except t
, t
, and t
. Part (b) of AC Test Loads and Waveforms used for t
, t
, and t
.
9. The parameters t
and t
are measured as the delay from the input disable logic threshold transition to V
OH
– 0.5V for an enabled HIGH output or V
OL
+
0.5V for an enabled LOW input.
10.t
, minimum guaranteed clock period is that guaranteed for state machine operation and is calculated from t
P
= t
S
+ t
CO
. The minimum guaranteed period for
registered data path operation (no feedback) can be calculated as the greater of (t
+ t
) or (t
+ t
).
11. f
, minimum guaranteed operating frequency, is that guaranteed for state machine operation and is calculated from f
MAX
= 1/(t
S
+ t
CO
). The minimum
guaranteed f
MAX
for registered data path operation (no feedback) can be calculated as the lower of 1/(t
