Note 2: Maximum and minimum limits over temperature are guaranteed by design and characterization. Devices are 100% tested
at T
A
= +25°C.
Note 3: Tolerance on all external resistors (including figures) is ±1%.
Note 4: Guaranteed by design and characterization.
Note 5: AC parameters are guaranteed by design and characterization and not production tested. Limits are set at ±6 sigma.
Note 6: C

is the magnitude of the difference of any differential propagation delays between devices operating under identical
conditions.
Note 10: t

is the magnitude of the difference of any differential propagation delays between devices operating over rated
conditions.
Note 11: Meets all AC specifications.
Note 12: Input jitter subtracted from output jitter.
