System Considerations
The power switching characteristics of Advanced
CMOS EPROMs require careful decoupling of the
devices. The supply current, I
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 falling and rising edges of E. The magnitude of
the transient current peaks is dependent on the
capacitive and inductive loading of the device at
the output. The associated transient voltage peaks
can be suppressed by complying with the two line

output control and by properly selected decoupling
capacitors. It is recommended that a 0.1µF ceram-
ic capacitor be used on every device between V
and V
tor of low inherent inductance and should be
placed as close to the device as possible. In addi-
tion, a 4.7µF bulk electrolytic capacitor should be
used between V
es. 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.
