DESCRIPTION/ORDERING INFORMATION  
This single positive edge triggered D-type flip-flop is designed for 1.65-V to 5.5-V VCC operation.  
A low level at the preset (PRE) or clear (CLR) input sets or resets the outputs, regardless of the levels of the  
other inputs. When PRE and CLR are inactive (high), data at the data (D) input meeting the setup time  
requirements is transferred to the outputs on the positive-going edge of the clock pulse. Clock triggering occurs  
at a voltage level and is not related directly to the rise time of the clock pulse. Following the hold-time interval,  
data at the D input can be changed without affecting the levels at the outputs.  
This device is fully specified for partial power down applications using Ioff. The Ioff circuitry disables the outputs,  
preventing damaging current backflow through the device when it is powered down.
