Pinout

The SN74HCT574PWR is a 20-pin integrated circuit from Texas Instruments. It is an octal D-type flip-flop with 3-state outputs. This device features edge-triggered D-type flip-flops with a direct clear input and is designed for asynchronous operation. When the clock input (CP) is held at a low-to-high transition, the state of the input data (D) is transferred to the corresponding output (Q). The flip-flops store the current data until the next clock input. The 3-state outputs can be disabled to provide bus operation by using the output enable (OE) pin. This allows for the connection of multiple outputs to a common bus line. The SN74HCT574PWR is typically used in situations where data needs to be stored temporarily and then transferred or shifted in digital circuits.
