Working Principles
CD74AC164M operates as a shift register, where data is shifted in serially and then outputted in parallel. The SER pin receives the serial input data, which is synchronized with the CLK signal. On each rising edge of the clock, the input data is shifted into the register, while the previously stored data is shifted to the next output. The QH' pin serves as the serial output, while the QH to QA pins provide the parallel outputs.
