NOTES:
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.

Note:
1. VIH(max) = 4.6V AC for pulse width ≤ 10ns acceptable.
2. VIL(min) = -1.5V AC for pulse width ≤ 10ns acceptable.
3. Any input 0V ≤ VIN ≤ VDD + 0.3V, all other pins are not under test = 0V.
4. Dout is disabled , 0V ≤ VOUT ≤ VDD.
