Working Principles
The CD74AC164ME4 is a serial-in, parallel-out shift register. It receives data serially through the SER pin and shifts it into the register on each clock pulse received at the CLK pin. The shifted data is then available in parallel form at the QH outputs. The MR pin allows for resetting the register to its initial state, while the output enable/disable control provides flexibility in controlling the output status.
