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
NOTES:
1.
V
REF
is expected to be equal to 0.5*V
CCQ
of the transmitting device, and to track variations in the dc level of same. Peak-to peak noise on V
REF
may not exceed +/-2% of the dc
value.
2.
V
TT
is not applied directly to the device. V
TT
is a system supply for signal termination resistors, is expected to be set equal to V
REF
, and must track variations in the DC level of
V
REF.
3.
V
ID
is the magnitude of the difference between the input level on CK and the input level on CK#.
4.
The ratio of the pullup current to the pulldown current is specified for the same temperature and voltage, over the entire temperature and voltage range, for device drain to source
voltages from 0.25V to 1.0V. For a given output, it represents the maximum difference between pullup and pulldown drivers due to process variation. The full variation in the ratio
of the maximum to minimum pullup and pulldown current will not exceed 1/7 for device drain to source voltages from 0.1 to 1.0.
