*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. Overshoot : Vcc+3.0v for pulse width less than 10ns.

2. Undershoot : Vss-3.0v for pulse width less than 10ns.

3. Overshoot and Undershoot are sampled, not 100% tested.
