Note 1:
Designers should take care to provide a minimum inductance path between the GND pins and system ground, to minimize noise.
Note 2:
Guaranteed by design.
Note 3:
When MA1–15, CAS, RAS0 and RAS1 are driven low, their voltages are below GND
a
0.2V, if less than 0.1 mA is driven. When OE, SEL1, WE0 and WE1
are driven high, their voltages are above V

Note 4:
The parameters I
