Detailed Pin Configuration

The 74HC165PW,112 has a total of 16 pins:

  1. SER (Serial Data Input)
  2. QH' (Serial Data Output)
  3. QH (Serial Data Output)
  4. GND (Ground)
  5. QA (Parallel Data Output)
  6. QB (Parallel Data Output)
  7. QC (Parallel Data Output)
  8. QD (Parallel Data Output)
  9. QE (Parallel Data Output)
  10. QF (Parallel Data Output)
  11. QG (Parallel Data Output)
  12. QH (Parallel Data Output)
  13. MR (Master Reset)
  14. SH/LD (Shift/Load)
  15. CLK (Clock Input)
  16. VCC (Supply Voltage)

Functional Features

  • Serial data is input through the SER pin and shifted into the shift register on each rising edge of the CLK signal.
  • The SH/LD pin controls the shift/load operation. When SH/LD is low, the data is shifted in; when it is high, the parallel data is latched.
  • The MR pin is used to reset the shift register to its initial state.
  • The QH' and QH pins provide serial data output.

Advantages and Disadvantages

Advantages: - High-speed operation allows for efficient data transfer. - Serial-in, parallel-out functionality enables easy interfacing with other devices. - Wide supply voltage range provides flexibility in various applications.

Disadvantages: - Limited number of parallel outputs (8 bits). - Requires an external clock signal for proper operation.

Working Principles

The 74HC165PW,112 is a synchronous shift register that can be used to convert serial data into parallel data. It operates based on the rising edge of the clock signal. When the SH/LD pin is low, the input data is shifted into the register. On the rising edge of the clock, the data is transferred from the shift register to the parallel outputs. The MR pin can be used to reset the shift register to its initial state.

Detailed Application Field Plans

The 74HC165PW,112 can be used in various applications, including but not limited to: - Data acquisition systems - Industrial automation - Communication systems - LED matrix control - Keypad scanning
