Note : Permanent device damage may occur if "ABSOLUTE MAXIMUM RATINGS" are exceeded.
Functional operation should be restricted to recommended operating condition.
Exposure to higher than recommended voltage for extended periods of time could affect device reliability.

Notes : 1. VIH (max) = 5.6V AC. The overshoot voltage duration is ≤ 3ns.
2. VIL (min) = -2.0V AC. The undershoot voltage duration is ≤ 3ns.
3. Any input 0V ≤ VIN ≤ VDDQ.
Input leakage currents include Hi-Z output leakage for all bi-directional buffers with Tri-State outputs.
