NOTES
(READ CYCLE)
1. WE is high for read cycle.
2. All read cycle timing is referenced from 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 with Load(B). 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 conditions is necessary during read and write cycle.
