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.

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
