Advantages and Disadvantages

Advantages: - High-speed operation - Easy integration into digital systems - Compact package size - Versatile applications

Disadvantages: - Limited number of parallel inputs - Requires external clock signal

Working Principles

The CD74HC165M96G4 operates based on the principle of sequential data processing. In the parallel load mode, the data present at the parallel inputs (D0-D7) is latched into the shift register when the SH/LD pin is set high. Once the data is loaded, the SH/LD pin is set low, and the clock signal applied to the CLK pin starts shifting the data out serially through the QH' pin.

Detailed Application Field Plans

The CD74HC165M96G4 finds applications in various fields, including:

  1. Data Acquisition Systems: Used for sequential sampling and processing of multiple input signals.
  2. Industrial Automation: Enables control and monitoring of multiple sensors and actuators.
