Notes:
1. V CC must be applied simultaneously or before V PP and removed simultaneously or after V PP .
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 50 μsec ± 5%.
