System Considerations
During the switch between active and standby conditions, transient
current peaks are produced on the rising and falling edges of Chip
Enable. The magnitude of these transient current peaks is
dependent on the output capacitance loading of the device. At a
minimum, a 0.1uF ceramic capacitor (high frequency, low inherent
inductance) should be used on each device between V
CC
and GND,
and between V
PP
and GND to minimize transient effects.
