NOTES:
1. VM~ meansAbsolute Maximum Voltage for input in the period of O.OV < Vcc < 2.0 V, Vi (CE#) is only
o.oov-v&fAx
2. The tDrand tpf are defined as “linear waveforms” in the period of 10% to 9010,or vice-versa. Even if the
waveform is not a “liner waveform,” its rising andfalling ime mustmeetthis specification.
