Working Principles

The 74HCT166N,652 operates as a parallel-in/serial-out shift register. The parallel data is loaded into the shift register through the DS (Serial Data Input) pin. The data is then shifted out serially through the Q7S (Serial Output) pin. The SHCP (Shift Register Clock Input) controls the shifting of data, while the STCP (Storage Register Clock Input) latches the shifted data into the storage register. The MR (Master Reset Input) clears both the shift and storage registers, and the OE (Output Enable Input) enables or disables the outputs.
