Working Principles

The 74HCT164BQ,115 operates based on the principle of serial-in, parallel-out shifting. The serial data input (SER) is shifted through the internal flip-flops with each clock pulse (CP). The parallel outputs (QA-QH) reflect the state of the internal flip-flops after each shift. The master reset (MR) pin can be used to clear the shift register, while the output enable (OE) pin controls the output stage.

Detailed Application Field Plans

The 74HCT164BQ,115 can be used in various digital electronics applications, including but not limited to:

1. Data communication systems
2. Serial-to-parallel data conversion
3. LED matrix displays
4. Control and interface circuits
5. Shift register-based counters
