74LVC1G74

The 74LVC1G74 is a single D-Type positive edge-triggered flip-flop with clear and preset functions. This device can operate in the supply voltage range from 1.65V to 5.5V. No matter what the levels of the other inputs are, the preset (PRE) input or clear (CLR) input can be pulled low to set or reset the outputs. When the preset input and clear input are held high, data at the D input that suffices for set-up time purposes is moved to the Q output on the low-to-high clock transition. After the hold time interval, data at the D input can be changed without any influence on output levels. Clock triggering appears at a voltage level which is uncorrelated with the rise time of the clock pulse.

This device is highly suitable for partial power-down applications by using power-off leakage current (IOFF) circuit.
