description/ordering information  
This 16-bit edge-triggered D-type flip-flop is  
designed for 1.65-V to 3.6-V V  
operation.  
CC  
A buffered output-enable (OE) input can be used to place the eight outputs in either a normal logic state (high  
or low logic levels) or the high-impedance state. In the high-impedance state, the outputs neither load nor drive  
thebuslinessignificantly. Thehigh-impedancestateandincreaseddriveprovidethecapabilitytodrivebuslines  
without interface or pullup components.  
OE does not affect internal operations of the flip-flop. Old data can be retained or new data can be entered while  
the outputs are in the high-impedance state.
