Notes

20. This part has an internal voltage regulator; t

POWER

is the time that the power is supplied above V

DD

minimum initially before a read or write operation can be initiated.

21. These parameters are extrapolated from the input timing parameters (t

KHKH

- 250 ps, where 250 ps is the internal jitter. An input jitter of 200 ps (t

KC Var

) is already

included in the t

KHKH

). These parameters are only guaranteed by design and are not tested in production.

22. t

CHZ

, t

CLZ

are specified with a load capacitance of 5 pF as in (b) of

AC Test Loads and Waveforms

. Transition is measured

±100 mV from steady-state voltage.

23. At any voltage and temperature t

CHZ

is less than t

CLZ

and t

CHZ

less than t

CO

.
