Working Principles

The CD74ACT299M96 operates based on the principles of sequential logic. It utilizes clock signals to synchronize the shifting or storing of data. When used as a shift register, the serial data input (SER) is shifted through the register upon each rising edge of the clock signal (CLK). The parallel data inputs (A, B, C, D) can be loaded into the register using the register clock input (RCLK). The stored data can then be retrieved from the outputs (Q0-Q7) or the synchronous output (Q7S).
