Notes:
27. Test conditions as specified with the output loading as shown in part (a) of AC Test Loads unless otherwise noted.
28. Output loading is specified with C
= 5 pF as in AC Test Loads.
29. At any given temperature and voltage condition, t
is less than t
, t
is less than t
and t
is less than t
.
30. OE is a
“
Don
’
t Care
”
after a write cycle begins To prevent bus contention, OE should be negated prior before the start of write cycle.
31. 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.
