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 0.1μF, high-frequency, low inherent inductance, ceramic capacitor should be utilized for each device. This
capacitor should be connected between the V CC and 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 4.7μF bulk electrolytic
capacitor should be utilized, again connected between the V CC and ground terminals. This capacitor should be positioned as
close as possible to the point where the power supply is connected to the array.
