Notes:

1. VIH(max) = VCC + 3.0V for pulse width less than 10ns.

2. VIL(min) = VSS - 3.0V for pulse width less than 10ns.

3. Over/Undershoot specifications are characterized, not 100% tested.

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℃
