This is a stress rating only and functional operation on the
device at these or any other conditions above those indicated
in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended
periods may affect reliability.
**Junction temperature depends upon package type, cycle time,
loading, ambient temperature and airflow. See the Application
Information section at the end of this datasheet for more infor-
mation.
ABSOLUTE MAXIMUM RATINGS*
Voltage of Vcc Supply Relative to Vss......................-.5V to +7V
Storage Temperature............................................-65°C to +150°C
Short Circuit Output Current(per I/O).................................20mA
Voltage on Any Pin Relative to Vss....................-.5V to Vcc+1V
Maximum Junction Temperature**...................................+150°C
*Stresses greater than those listed under “Absolute Maximum
Ratings” may cause permanent damage to the device.

NOTES
1. All voltages referenced to VSS (GND).
2. -2V for pulse width <20ns.
3. ICC is dependent on output loading and cycle rates.
7. At any given temperature and voltage condition,
tHZCS, is less than tLZCS, and tHZWE is less than tLZWE
8. WE\ is HIGH for READ cycle.
.
9. Device is continuously selected. Chip selects and output
enable are held in their active state.
10. Address valid prior to or coincident with latest occurring
chip enable.
11. tRC= READ cycle time.
12. Chip enable (CS\) and write enable (WE\) can initiate and
terminate a WRITE cycle.
