Working Principles

The 74LV165D/AUJ is a shift register that can store and transfer data in a serial-in, parallel-out manner. It operates synchronously with a clock pulse input (CP). When the clock pulse rises, the data at the serial data input (SER) is shifted into the register. The previously stored data is shifted to the next stage, and the last stage's data appears at the parallel data output (QH). The master reset (MR) input clears the register, setting all outputs to a known state. The output enable (OE) input controls the tri-state outputs, allowing them to be disabled when necessary.

Detailed Application Field Plans

The 74LV165D/AUJ is commonly used in various applications, including:

1. Data acquisition systems
2. Serial-to-parallel conversion
3. Parallel data storage and retrieval
4. Shift register-based control circuits
5. Communication interfaces
6. LED matrix displays
7. Digital signal processing
