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 values are measured at VCC = VCC(TYP.) and TA = 25
5. This parameter is measured at VCC = 3.0V
