Working Principles

The CD74HCT165M96E4 operates as an 8-bit parallel-in/serial-out shift register. It receives data in parallel format through the parallel inputs (QA to QH) and stores it internally. The data can then be shifted out serially through the QH' pin using the clock input (CLK). The shift/load input (SH/LD) determines whether the data is shifted or loaded into the register. The output enable (OE) pin enables or disables the outputs, while the master reset (MR) pin resets the shift register to its initial state.

Detailed Application Field Plans

The CD74HCT165M96E4 can be used in various applications that require data storage and serial data transfer. Some potential application fields include:

  1. Data Communication Systems: The shift register can be used for serial-to-parallel or parallel-to-serial data conversion in communication systems.
  2. Industrial Automation: It can be utilized in control systems for data storage and manipulation.
  3. Display Systems: The shift register can be employed in LED or LCD display systems for controlling the display of characters or images.
  4. Data Logging: It can be used in data logging systems to store and transmit sensor data.
