*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.

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 be exceeded if certain precautions are observed (consult application notes), and which may
overshoot to +7.0V for pulses of less than 20ns.

Notes:
1. X Can be V IL or V IH .
2. Read, output disable, and standby modes require 2.7V ? V CC ? 3.6V or 4.5V ? V CC ? 5.5V.
3. Refer to programming characteristics. Programming modes requires V CC = 6.5V.
4. V H = 12.0 ± 0.5V.
5. 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.
