*Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device or any other conditions above those indicated in the operational sections of this specification is
not implied. Exposure to the absolute maximum rating conditions for extended period may affect device reliability.

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℃
