*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 + 3.0V for pulse width less than 10ns. VIL(min) = VSS - 3.0V for pulse width less than 10ns.
2. Over/Undershoot specifications are characterized, not 100% tested.
3. Typical values are included for reference only and are not guaranteed or tested.
Typical valued are measured at VCC = VCC(TYP.) and TA = 25?
