is ideal for providing More Battery Life™ (MoBL ) in portable
applications such as cellular telephones. The device also has an
automatic power down feature that significantly reduces power
consumption when addresses are not toggling. Placing the
device in standby mode reduces power consumption by more
than 99 percent when deselected (CE HIGH). The input and
