An EPROM's power switching characteristics require careful device decoupling. System designers are
interested in three supply current issues: standby current levels (I
transient current peaks produced by the falling and rising edges of ALE Transient current magnitudes
depend on the device output's capacitive and inductive loading. Proper decoupling capacitor selection
will suppress transient voltage peaks. Each device should have a
0.1
μ
F ceramic capacitor connected between its V
inductance capacitor should be placed as close as possible to the device. Additionally, for every eight
devices, a 4.7
μ
F electrolytic capacitor should be placed at the array's power supply connection
between V
