Working Principles

The 74LVC574ABQ,115 is an octal D-type flip-flop that stores and transfers data based on clock pulses. When the clock pulse (CP) is triggered, the input data (D0-D7) is latched and stored in the respective flip-flops. The stored data can then be accessed from the output pins (Q0-Q7). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.

The master reset (MR) pin allows all flip-flops to be cleared simultaneously, resetting the stored data to a known state. This IC operates within a supply voltage range of 1.65V to 5.5V, making it suitable for various low-voltage applications.
