NOTES:
1. See AC Input/Output Reference Waveform for timing measurements.
2. OE# may be delayed up to tCE–tOE after the falling edge of CE# without impact on tCE.
3. Sampled, but not 100% tested.
4. tFLQV, BYTE# switching low to valid output delay will be equal to tAVQV, measured from the time DQ15/A–1 becomes valid.
5. See Test Configurations (Figure 22), 2.7V–3.6V and 3.3 ± 0.3V Standard Test component values.
6. See Test Configurations (Figure 22), 5V Standard Test component values.
7. The specification tPLPH is the minimum time RP# must be held low to produce a valid reset of the device.
