3 / 9 page AT27C1024 3 Block Diagram Absolute Maximum Ratings* Temperature Under Bias ...................... -55 °C to +125°C *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 condi- tions beyond those indicated in the operational sec- tions of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note: 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 overshoot to +7.0V for pulses of less than 20 ns. Storage Temperature............................ -65 °C to +150°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) Operating Modes Notes: 1. X can be VIL or VIH. 2. Refer to Programming Characteristics. 3. VH = 12.0 ± 0.5V. 4. Two identifier words 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 word and high (VIH) to select the Device Code word. 5. Standby VCC current (ISB) is specified with VPP = VCC. VCC > VPP will cause a slight increase in ISB.
