Stresses beyond those listed under
“
absolute maximum ratings
”
may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under
“
recommended operating conditions
”
is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. The input and output negative voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
2. This value is limited to 3.6 V maximum.
3. The package thermal impedance is calculated in accordance with JESD 51.

NOTES:
4. Unused inputs must be held high or low to prevent them from floating.
5. DC input signal voltage specifies the allowable dc execution of differential input.
6. Differential input signal voltage specifies the differential voltage |VTR
–
VCP| required for switching, where VTR is the true input level
and VCP is the complementary input level.
7. Differential cross-point voltage is expected to track variations of VDDQ and is the voltage at which the differential signals must be
crossing.
