DESCRIPTION
This single positive-edge-triggered D-type flip-flop is
designed for 1.65-V to 5.5-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 level at the output.
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.
