3. Switching Considerations

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

sient voltage excursions. 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_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

connected 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*

*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.
