• Sensitivity to voltage fluctuations may require additional voltage regulation circuitry in some cases.

Working Principles

The CD74ACT164E operates based on the principle of shifting data through its internal registers. The serial data input (SER) is clocked into the shift register on each rising edge of the clock input (CLK). The shifted data is then available at the parallel output pins (QA-QH). The master reset (MR) input can be used to clear the shift register to a known state.

Application Field Plans

The CD74ACT164E can be utilized in various applications, including but not limited to:

1. Data communication systems
2. Digital displays
3. Serial-to-parallel data conversion
4. Data storage and retrieval systems
5. Industrial automation control systems
