DESCRIPTION/ORDERING INFORMATION
This single positive-edge-triggered D-type flip-flop is operational at 0.8-V to 2.7-V V_CC, but is designed
specifically for 1.65-V to 1.95-V V_CC 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 I_off. The I_off circuitry disables the outputs,
preventing damaging current backflow through the device when it is powered down.
