Unless accommodated by the system design, these transients may exceed datasheet limits, resulting in device non-conformance. At a minimum, a 0.1 µF high frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This capacitor should be connected between the V CC and Ground terminals of the device, as close to the device as possible. Additionally, to stabilize the supply voltage level on printed circuit boards with large EPROM arrays, a 4.7 µF bulk electrolytic capacitor should be utilized, again connected between the V CC and Ground terminals. This capacitor should be positioned as close as possible to the point where the power supply is connected to the array. 4. Block Diagram 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 V CC + 0.75V DC which may overshoot to +7.0 volts for pulses of less than 20 ns. 5. Absolute Maximum Ratings* Temperature Under Bias............................... -55°C to + 125°C *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating only and func- tional operation of the device at these or any other conditions beyond those indicated in the opera- tional sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 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) |
