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.  
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.  
NanoStar™ and NanoFree™ package technology is a major breakthrough in IC packaging concepts, using the  
die as the package.  
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.

(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).
