Notes:

1. VIH(max) = VCC + 2.0V for pulse width less than 6ns.

2. VIL(min) = VSS - 2.0V for pulse width less than 6ns.

3. Over/Undershoot specifications are characterized on engineering evaluation stage, not for mass production test.

4. Typical values are included for reference only and are not guaranteed or tested.

Typical valued are measured at VCC = VCC(TYP.) and TA = 25℃
