3 / 9 page 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 Maxi- mum 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 indi- cated 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 out- put pin voltage is VCC + 0.75V dc which may be ex- ceeded if certain precautions are observed (consult application notes) and which may overshoot to +7.0V for pulses of less than 20 ns.

X can be VIL or VIH. 2. Read, output disable, and standby modes require, 2.7V ≤ 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 tog- gled low (VIL) to select the Manufacturer’s Identification byte and high (VIH) to select the Device Code byte.
