Working Principles

The 74HCT166D,653 is a serial-in, parallel-out shift register. It receives data serially through the SER pin and shifts it into the register on each rising edge of the CLK input. The SH/LD pin controls the mode of operation. When SH/LD is low, the data is shifted in; when it is high, the parallel load mode is enabled, and the data present at the inputs is loaded into the register.

The MR pin is an asynchronous master reset that clears the register to its initial state when activated. The OE pin is used to enable or disable the outputs. When OE is low, the outputs are active; when it is high, the outputs are disabled.
