Working Principles

SN74HC164DT operates based on the principle of serial-to-parallel data conversion. It receives a serial data input (SER) and shifts it into its internal shift register upon receiving clock pulses (CP). The shifted data is then available at the parallel output pins (QA to QH). The master reset (MR) pin can be used to clear the register, and the cascading feature allows multiple SN74HC164DT devices to be connected for larger shift registers.
