10 CE or WE must be High during address transitions. Either CE or WE asserting high terminates a write cycle.
11
All write cycle timings are referenced from the last valid address to the first transitioning address.
12 Not applicable.
13 C = 30pF, except on High Z and Low Z parameters, where C = 5pF.
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, B, C.
t
CLZ
and t
CHZ
are specified with C
L
= 5pF as in Figure C. Transition is measured ±500mV from steady-state voltage.
This parameter is guaranteed, but not tested.
WE is High for read cycle.
CE and OE are Low for read cycle.
Address 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.
