Notes
1. Slope measured at any point on VDD waveform.
2. After power up, when EN goes high the nonvolatile latches are read and the values restored to the outputs QN.
3. After power up, this is the minimum time required before a state change operation may occur. EN and VDD may be
coincident at power up, and in this case tEHFC time is referenced to VDD (min) and CLK .
