Working Principles

The 74AHC374PW,112 is an octal D-type flip-flop with 3-state outputs. It operates based on the clock signal provided at the CLK pin. When the clock signal transitions from low to high, the input data at the D0-D7 pins is latched and stored in the flip-flop. The stored data is then available at the Q0-Q7 output pins.

The 3-state outputs allow the IC to disconnect from the bus lines when not actively driving them. This feature prevents conflicts and allows multiple devices to share the same bus.
