SystemConsiderations
The power switching characteristics of Advanced
CMOS EPROMs require careful decoupling of the
devices. The supply current, I
CC
, has three seg-
ments that are of interest to the system designer :
the standby current level, the active current level,
and transient current peaks that are produced by
the fallingand risingedges of E. The magnitude of
the transient current peaks is dependent on the
capacitiveandinductiveloadingofthedeviceatthe
output.
The associated transient voltage peaks can be
suppressed by complying with the two line output
control and by properly selected decoupling ca-
pacitors. It is recommended that a 0.1
μ
F ceramic
capacitor be used on every device between V
CC
andV
SS
. Thisshouldbe ahigh frequencycapacitor
of low inherent inductance and should be placed
as close to the device as possible. In addition, a
4.7
μ
F bulk electrolytic capacitor should be used
betweenV
CC
and V
SS
for everyeight devices.The
bulk capacitor should be located near the power
supply connection point.The purpose of the bulk
capacitor is to overcome the voltage drop caused
by the inductive effects of PCB traces.
