description/ordering information
This dual positive-edge-triggered D-type flip-flop is designed for 1.65-V to 5.5-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.
