Note:
1. Stress greater than those listed may cause permanent damage to the device. This is a stress rating only, and device
functional operation at or above the conditions indicated is not implied. Expousure to absolute maximum rating con
ditions for extended periods may affect reliablility.

Note:
1. V_DDQ must be less than or equal to V_DD.
2. Peak to peak ac noise on V_REF may not exceed +/-2% V_REF(dc)
3. VTT of transmitting device must track VREF of receiving device.
