DESCRIPTION/ORDERING INFORMATION  
This single positive-edge-triggered D-type flip-flop is operational at 0.8-V to 2.7-V VCC, but is designed  
specifically for 1.65-V to 1.95-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. To better optimize the flip-flop for  
higher frequencies, the CLR input overrides the PRE input when they are both low.  
NanoStar™ and NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the  
die as the package.

(2) DCT: The actual top-side marking has three additional characters that designate the year, month, and assembly/test site.  
DCU: The actual top-side marking has one additional character that designates the assembly/test site.  
YEP/YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following  
character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb, = Pb-free).
