Notes:
23. Test conditions as specified with the output loading as shown in part (a) of AC Test Loads unless otherwise noted.
24. At any given temperature and voltage condition, t
is less than t
KQLZ
and t
OEHZ
is less than t
OELZ
.
25. OE is a
“
don
’
t care
”
when a byte write enable is sampled LOW.
26. This is a synchronous device. All synchronous inputs must meet specified set-up and hold time, except for
“
don
’
t care
”
as defined in the truth table.
