NOTES:
1. ViMAx means Absolute Maximum Voltage for input in the period of O.OV < Vcc < 2.0 V, Vi (CE#) is only
o.oov-ViMAX
2. The tpr and tpr are defined as “linear waveforms” in the period of 10% to 90%, or vice-versa. Even if the
waveform is not a “liner waveform,” its rising and falling time must meet this specification.
