Note : Permanent device damage may occur if ABSOLUTE MAXIMUM RATING 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. VDDQ must not exceed the level of VDDQ.

2.VIL(min)=-0.9V with a pulse width ≦ 5ns .

3.Any input 0V ≦ VIN ≦ 3.6V, all other pins are not under test = 0V.

4.Dout is disabled, 0V ≦ VOUT ≦ 2.7V.

5. VREF is expected to be equal to 0.5* VDDQ of the transmitting device, and to track variations in the DC level of

the same. Peak to peak noise on VREF may not exceed ±2% of the DC value.
