| VCC Setup Time | tVCS | 2 | — | μs | |
| CE Program Pulse Width(4) | tPW | 95 | 105 | μs | |
| Data Valid From CE(3) | tDV | — | 1 | μs | |

Note:
- TA = +25 ± 5°C, VCC= 6.5 ± 0.25V, OE/VPP = 13.0 ± 0.25V.
- VCC must be applied simultaneously with or before OE/VPP and removed simultaneously with or after OE/VPP.
- This parameter is only sampled, and is not 100% tested. Output float is defined as the point where data is no longer driven. See timing diagram.
- Program pulse width tolerance is 100 μs ± 5%.
