Notes: 1. V_CCmust be applied simultaneously or before V_PPand 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 100 µsec ±5%.
