*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
VCC + 0.75V DC, which may overshoot to +7.0V for pulses of less than 20ns.

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