description/ordering information  
This dual positive-edge-triggered D-type flip-flop is designed for 1.65-V to 5.5-V V  
operation.  
CC  
When data at the data (D) input meets the setup time requirement, the data is transferred to the Q output on  
the positive-going edge of the clock pulse. Clock triggering occurs at a voltage level and is not directly related  
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.  
NanoStarand NanoFreepackage technology is a major breakthrough in IC packaging concepts, using the  
die as the package.

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).
