mon connection to all devices in the array and
connected to the READ line from the system control
bus. This assures that all deselected memory devices
are in their low-power standby mode and that the out-
put pins are only active when data is desired from a
particular memory device.
System Applications
During the switch between active and standby condi-
tions, transient current peaks are produced on the ris-
ing and falling edges of Chip Enable. The magnitude of
these transient current peaks is dependent on the out-
put capacitance loading of the device. At a minimum, a
0.1 μF ceramic capacitor (high frequency, low inherent
inductance) should be used on each device between
V
CC
and V
SS
to minimize transient effects. In addition,
to overcome the voltage drop caused by the inductive
effects of the printed circuit board traces on EPROM ar-
rays, a 4.7 μF bulk electrolytic capacitor should be used
between V
CC
and V
SS
for each eight devices. The loca-
tion of the capacitor should be close to where the
power supply is connected to the array.
