Working Principles

The 74HCT165DB,118 is a serial-in, parallel-out shift register. It receives data serially through the SER pin and shifts it into its internal storage register on each rising edge of the CLK input. The SH/LD pin controls the shift/load operation. When SH/LD is low, the device is in the shift mode, allowing data to be shifted in. When SH/LD is high, the device is in the load mode, latching the data from the internal storage register onto the parallel outputs.
