SystemConsiderations
The power switching characteristics of Advanced
CMOS EPROMsrequire careful decouplingof 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
thefalling andrising edgesof E. Themagnitudeof
the transient current peaks is dependent on the
output capacitiveand inductive loading of the de-
vice.
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
. Thisshouldbea highfrequencycapacitor
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
andV
SS
for everyeightdevices. The
bulk capacitor should be located near the power
supply connection point.The purpose of the bulk
capacitoris to overcome the voltage drop caused
by the inductiveeffectsof PCBtraces.
