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
Maximum Ratings” may cause permanent dam-
age to the device. This is a stress rating only and
functional operation of the device at these or any
other conditions beyond those indicated in the
operational sections of this specification is not
implied. Exposure to absolute maximum rating
conditions for extended periods may affect device
reliability.
Note:
Maximum voltage is -0.6V dc which may undershoot
to -2.0V for pulses of less than 20 ns. Maximum out-
put pin voltage is VCC + 0.75V dc which may over-
shoot to +7.0V for pulses of less than 20 ns.

3. VH = 12.0 ± 0.5V.
4. 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 Identification word and high (VIH) to select the Device Code word.
5. Standby VCC current (ISB) is specified with VPP = VCC. VCC > VPP will cause a slight increase in ISB.
