Vcc must be applied simultsneously or before Vpp and removed simultaneously or after Vpp.2. The length of the overprogram pulse may vary from 2.85msec to 78.75msec as a function of the iteration counter value X.3. Intlial Program Pulse width tolerance is Imsec =5%.4. This parameter is only sampled and not 100% tested.Output Float is defined as the point where data is no longer driven (see timing diagram).7110151
