NOTE:
1. I
DD
is specified with no output current and increases with faster cycle times. I
DD
Q increases with faster cycle times and
greater output loading.
2. “ Device deselected” means device is in power-down mode as defined in the truth table. “ Device selected” means
device is active (not in power-down mode).
3. Typical values are measured at 3.3V, 25oC and 15ns cycle time.
4. This parameter is sampled.
