3. System Considerations

Switching between active and standby conditions via the Chip Enable pin may produce transient

voltage excursions. Unless accommodated by the system design, these transients may exceed

datasheet limits, resulting in device nonconformance. 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_CCand 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 con-

nected between the V_CCand Ground terminals. This capacitor should be positioned as close as

possible to the point where the power supply is connected to the array.

5. Absolute Maximum Ratings*

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

*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.

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⁾

V_PPSupply Voltage with

Respect to Ground .......................................-2.0V to +14.0V⁽¹⁾

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

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