Working Principles
The CD74AC164E is a CMOS shift register that performs serial-in, parallel-out data conversion. It consists of eight flip-flops connected in series, allowing the input data to be shifted through each stage with the help of an external clock signal. The serial data is loaded into the first flip-flop (QH') and then sequentially transferred to the subsequent stages on each clock pulse. The parallel outputs (QH-QB) provide the converted data in parallel format.
Detailed Application Field Plans
The CD74AC164E shift register finds applications in various digital systems where data needs to be converted from serial to parallel format. Some common application areas include:
- Data communication systems
- Serial-to-parallel data conversion
- LED matrix displays
- Digital counters and timers
- Address decoding circuits
- Serial data storage and retrieval systems
