PRELIMINARY
Shaded areas contain advance information.
Notes:
7.
Cross Levels are VDD – 0.2V< VZ<0.2V.
8.
Deselection for a port occurs if CE0 is HIGH or if CE1 is LOW.
9.
fMAX = 1/tRC = All inputs cycling at f = 1/tRC (except Output Enable). f = 0 means no address or control lines change. This applies only to inputs at CMOS level
standby ISB3.
10. Tested initially and after any design or process changes that may affect these parameters.
