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 CL = 50 pF.
3. t
LZ
(max) 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
define CKE setup time to CLK rising edge except power down exit command.
