Note: Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is stress

rating only, and functional operation of the device at these or any other conditions above those indicated in the operational sections of

this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.

Note:

1. Inputs are not recognized as valid until VREF stabilizes.

2. VREF is expected to be equal to 0.5 V DDQ 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.

3. VDDQ tracks with VDD, VDDL tracks with VDD.

4. VTT of transmitting device track VREF of receiving device.
