Detailed Pin Configuration
The 74LV165APW,118 has a total of 16 pins:
- SER (Serial Data Input)
- QA (Parallel Output A)
- QB (Parallel Output B)
- QC (Parallel Output C)
- QD (Parallel Output D)
- QE (Parallel Output E)
- QF (Parallel Output F)
- QG (Parallel Output G)
- QH (Parallel Output H)
- MR (Master Reset)
- SH/LD (Shift/Load)
- CLK (Clock Input)
- GND (Ground)
- QH' (Complementary Output H)
- QG' (Complementary Output G)
- 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. When SH/LD is high, the parallel data is loaded into the shift register.
- The MR pin is used to asynchronously reset the shift register to its initial state.
- The parallel outputs (QA-QH) reflect the data stored in the shift register.
Advantages and Disadvantages
Advantages: - High-speed operation - Wide operating voltage range - Low power consumption - Small package size
Disadvantages: - Limited number of parallel outputs (8 in this case) - Lack of built-in output latches
Working Principles
The 74LV165APW,118 is a synchronous serial-in, parallel-out shift register. It stores and shifts data bits on each clock cycle. The shift/load control allows for either shifting or loading of data into the shift register. The master reset pin resets the shift register to its initial state.
