During V
CC
power-up, a pull-up resistor to V
CC
on
CE
is required to meet I
SB
specification.
This parameter is sampled, but not 100% tested.
For test conditions, see
AC Test Conditions
, Figures A and B.
t
CLZ
and t
CHZ
are specified with CL = 5 pF, as in Figure B. Transition is measured
±
500 mV from steady-state voltage.
This parameter is guaranteed, but not 100% tested.
WE
is high for read cycle.
CE
and
OE
are low for read cycle.
Address is valid prior to or coincident with
CE
transition low.
All read cycle timings are referenced from the last valid address to the first transitioning address.
All write cycle timings are referenced from the last valid address to the first transitioning address.
