AC CHARACTERISTICS—READ CYCLE
(V
CC
= 5V ± 10%, All Temperature Ranges)
(2)
Notes:
5.
CE
is LOW and
WE
is HIGH for READ cycle.
6.
WE
is HIGH, and address must be valid prior to or coincident with
CE
transition LOW.
7. Transition is measured ±200mV from steady state voltage prior to
change with specified loading in Figure 1. This parameter is sampled
and not 100% tested.
8. Read Cycle Time is measured from the last valid address to the first
transitioning address.
