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 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
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

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
