Working Principles
The SN74HC165PWT is a serial-in, parallel-out shift register. It stores and transfers data in an 8-bit format. The device operates based on the clock input signal. When the shift/load input is low, the device shifts the data from the serial input to the parallel outputs on each rising edge of the clock signal. When the shift/load input is high, the device loads the data from the serial input into the parallel outputs on the rising edge of the clock signal.
Detailed Application Field Plans
The SN74HC165PWT can be used in various applications that require data storage and transfer. Some potential application fields include:
- Data acquisition systems
- Industrial automation
- Robotics
- Communication equipment
