Notes (Read Cycle)
1. WE are 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 tOHZ are defined as the time at which the outputs achieve the open circuit condition referenced to VOH or VOL levels.
4. At any given temperature and voltage condition
t
HZ (max.) is less than tLZ (min.) both for a given device and from device to
device.
5. Transition is measured + 200mV from steady state voltage with load. This parameter is sampled and not 100% tested.
6. Device is continuously selected with CE = VIL.
7. Address valid prior to coincident with CE transition Low.
8. For common I/O applications, minimization or elimination of bus contention conditions is necessary during read and write
cycle.
9. For test conditions, see AC Test Condition, Figure A.
