Note 3 : Hatching indicates the state is "don't care".
4 : Writing is executed in ov erlap of /S and /W low.
5 : If /W goes low simultaneously with or prior to /S, the outputs remain in the high impedance state.
6 : Don't apply inv erted phase signal externally when DQ pin is output mode.
7 : ten, tdis are periodically sampled and are not 100% tested.
(Note 3)
Transition is measured ±500mV from steady
state voltage. (for ten,tdis)
