Ratings
-1.3V to VCC+2.0V (Note)
0°C to 70°C
-65°C to 125°C
Note: Minimum DC voltage on input or I/O pins is -0.5V.
During voltage transitions, inputs may undershoot VSS
to -1.3V for periods of up to 20ns. Maximum DC voltage on input or I/O pins is VCC+0.5V. During voltage
transitions, input may overshoot VCC to VCC+2.0V for
periods of up to 20ns.

1.9
Description
1) Added Block Diagram.
2) Added note to describe the minimum and maximum overshoot
ranges.
3) Changed page mode access time (tPA) and output enable time
(tOE) as 45ns instead of 50ns.
4) Added 100ns speed grade.
