Absolute Maximum Ratings*

Temperature Under Bias .................................. -40°C to +85°C

Storage Temperature ..................................... -65°C to +125°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:

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 be exceeded if certain precautions are observed (consult application notes) and which may

overshoot to +7.0 volts for pulses of less than 20 ns.

Notes:

1. X can be VIL or VIH.

2. Read, output disable, and standby modes require, 3.0V ≤ 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 bytes 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 byte and high (VIH) to select the Device Code byte.
