1. A write occurs during the overlap of E low and W low.
2. E1 and E2 are represented by E in this data sheet. E2 is of opposite polarity to E.
3. If G goes low coincident with or after W goes low, the output will remain in a high impedance state.
4. All timings are referenced from the last valid address to the first transitioning address.
5. If G
6. At any given voltage and temperature, t WLQZ (max) is less than t WHQX (min), both for a given device and from device to device.
7. Transition is measured 500 mV from steady–state voltage with load of Figure 1B.
8. This parameter is sampled and not 100% tested.
