NOTES:
1. W is high for read cycle.
2. For common I/O applications, minimization, or elimination of bus contention conditions is necessary during read and write cycles.
3. Device is continuously selected (E = VIL, G = VIL, and LB and/or UB = VIL).
4. Addresses valid prior to or coincident with E going low.
5. All read cycle timings are referenced from the last valid address to the first transitioning address.
6. Transition is measured 200 mV from steady–state voltage.
7. At any given voltage and temperature, tEHQZ (max) < tELQX (min), and tGHQZ (max) < tGLQX (min), both for a given device and from
device to device.
8. This parameter is sampled and not 100% tested.
