Absolute Maximum Ratings*
Temperature Under Bias ................ -55°C to +125°C
Storage Temperature...................... -65°C to +150°C
Voltage on Any Pin with
Respect to Ground......................... -2.0V to +7.0V (1)
Voltage on A9 with
Respect to Ground ...................... -2.0V to +14.0V (1)
VPP Supply Voltage with
Respect to Ground....................... -2.0V to +14.0V (1)
*NOTICE: Stresses beyond those listed under “Absolute Maxi-
mum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions beyond those indi-
cated in the operational sections of this specification is not
implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.
Note:
1. Minimum voltage is -0.6V dc which may undershoot to
-2.0V for pulses of less than 20 ns. Maximum output
pin voltage is VCC + 0.75V dc which may overshoot
to +7.0V for pulses of less than 20 ns.

Notes: 1. X can be VIL or VIH.
2. Read, output disable, and standby modes require,
2.7V ≤ VCC ≤ 3.6V, or 4.5V ≤ VCC ≤ 5.5V.
3. Refer to Programming Characteristics. Programming
modes require VCC = 6.5V.
4. VH = 12.0 ± 0.5V.
5. Two identifier words may be selected. All Ai inputs
are held low (VIL), except A9 which is set to VH and A0
which is toggled low (VIL) to select the Manufacturer’s Identi-
fication word and high (VIH) to select the Device Code word.
