Notes:
1. V
CC must be applied simultaneously or before OE/VPP and removed simultaneously or after OE/VPP.
2. 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.
3. Program Pulse width tolerance is 100 µsec ± 5%.
16. AC Programming Characteristics
T
A = 25 ± 5°C, VCC = 6.5 ± 0.25V, OE/VPP = 13.0 ± 0.25V
