Working Principles
The SN74ALS667DWRE4 is a 16-bit shift register with parallel load functionality. It can store and shift data in a serial manner while also allowing for parallel loading of data. The clock input controls the shifting of data, and the parallel/serial control input determines whether the data is loaded in parallel or shifted serially.
When the parallel/serial control input is set to parallel mode, the data present at the parallel inputs (QA-QH) is loaded into the register on the rising edge of the clock signal. In serial mode, the data is shifted through the register on each rising edge of the clock signal.
The output enable input allows for controlling the output state. When the output enable is low, the outputs are enabled and reflect the current state of the register. When the output enable is high, the outputs are disabled and remain in a high-impedance state.
