System 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

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

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

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 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 abso-

lute maximum rating conditions for extended

periods may affect device reliability.
