Notes: 1. AC measurement assumes t
T
= 1 ns. Reference level for timing of input signals is 1.5 V.
2. Access time is measured at 1.5 V. Load condition is C
L
= 50 pF.
3. t
LZ
(min) defines the time at which the outputs achieves the low impedance state.
4. t
HZ
(max) defines the time at which the outputs achieves the high impedance state.
5. t
CES
defines CKE setup time to CK rising edge except power down exit command.
