Working Principles

The CD74HC166MT is a serial-in, parallel-out shift register. It receives data serially through the SER pin and shifts it into the register on each rising edge of the CLK input. The parallel data is then available at the QA-QH outputs. The MR pin can be used to clear the register and start a new data sequence.

Detailed Application Field Plans

The CD74HC166MT can be used in various applications, including:

Data communication systems
Serial-to-parallel data conversion
LED matrix control
Digital displays
Industrial automation
Robotics
Automotive electronics
