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 not 100% tested
4 See Standard Test Configuration
5 tFLQV BYTE switching low to valid output delay will be equal to tAVQV from the time DQ15 Ab1 becomes valid
