Notes
22.This part has a voltage regulator internally; t
POWER
is the time that the power must be supplied above V
DD
minimum initially before a read or write operation can be
initiated.
23.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
) ia already
included in the t
KHKH
). These parameters are only guaranteed by design and are not tested in production
24.t
CHZ
, t
CLZ
, are specified with a load capacitance of 5 pF as in (b) of AC Test Loads and Waveforms on page 22. Transition is measured ± 100 mV from steady-state voltage.
25.At any voltage and temperature t
CHZ
is less than t
CLZ
and t
CHZ
less than t
CO
