*NOTICE:
Stresses beyond those listed under “Absolute
maximum 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 indicated in the operational sections of
this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may
affect device reliability.
Voltage on A9 with
respect to ground . . . . . . . . . . . . . . . . . -2.0V to +14.0V (1)
V PP supply voltage with
respect to ground . . . . . . . . . . . . . . . . . . -2.0V to +14.0V (1)
Note:
1. Minimum voltage is -0.6V DC, which may undershoot to -2.0V for pulses of less than 20ns. Maximum output pin voltage is
V CC + 0.75V DC, which may overshoot to +7.0V for pulses of less than 20ns.

Notes:
1. X can be V IL or V IH .
2. Refer to programming characteristics.
3. V H = 12.0 ± 0.5V.
4. Two identifier bytes may be selected. All Ai inputs are held low (V IL ) except A9, which is set to V H , and A0, which is tog-
gled low (V IL ) to select the manufacturer’s identification byte and high (V IH ) to select the device code byte.
