Working Principles

The CD74HC166M96 is a CMOS shift register that operates based on clock signals. It can be used to convert data between parallel and serial formats. When the SH/LD pin is low, the device is in shift mode, where data is shifted through the register with each clock pulse. When the SH/LD pin is high, the device is in load mode, allowing parallel data to be loaded into the register. The output data can be read from the QH' pin in serial format or from the QA-QH pins in parallel format.

Detailed Application Field Plans

The CD74HC166M96 can be utilized in various applications, including:

1. Serial Data Communication Systems
2. Data Acquisition Systems
3. Industrial Automation
4. LED Display Control
5. Digital Signal Processing
