1. W is high for read cycle.
2. E1 and E2 are represented by E in this data sheet. E2 is of opposite polarity to E.
3. All timings are referenced from the last valid address to the first transitioning address.
4. Addresses valid prior to or coincident with E going low.
5. At any given voltage and temperature, t EHQZ (max) is less than t ELQX (min), and t GHQZ (max) is less than t GLQX (min), both for a
6. Transition is measured 500 mV from steady–state voltage with load of Figure 1B.
7. This parameter is sampled and not 100% tested.
8. Device is continuously selected (E1 = V IL , E2 = V IH , G = V IL ).

minimum or a maximum limit for each param-
eter. Input requirements are specified from
the external system point of view. Thus, ad-
dress setup time is shown as a minimum
since the system must supply at least that
much time (even though most devices do not
require it). On the other hand, responses from
the memory are specified from the device
point of view. Thus, the access time is shown
as a maximum since the device never pro-
vides data later than that time.
The table of timing values shows either a
