Read Cycle Notes:
1.
WE is high for read cycle.
2.
All read cycle timing is referenced form the last valid address to the first transition address.
3.
t
HZ
and t
OHZ
are defined as the time at which the outputs achieve the open circuit condition and are not
referenced to V
OH
or V
OL
levels.
4.
At any given temperature and voltage condition, t
HZ(max)
is less than t
LZ(min)
both for a given device and
from device to device.
5.
Transition is measured + 200mV from steady state voltage. This parameter is sampled and not 100%
tested.
6.
Device is continuously selected with CS = V
IL.
7.
Address valid prior to coincident with CS transition low.
8. For common I/O applications, minimization or elimination of bus contention condition is necessary dur-
ing read and write cycle.
