Notes: 1. VCC 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%.
