Working Principles

The 74AHC374D,112 is a positive-edge-triggered flip-flop. It stores and transfers data based on the clock input signal. When the clock input transitions from low to high, the data present at the inputs (D0-D7) is latched and transferred to the corresponding outputs (Q0-Q7). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.

Detailed Application Field Plans

The 74AHC374D,112 can be used in various applications, including:

  1. Microprocessor Systems: Used for address and data bus interfacing.
  2. Memory Modules: Enables data storage and retrieval in memory devices.
  3. Communication Systems: Facilitates data transmission and reception.
  4. Industrial Control Systems: Provides control logic for automation processes.
  5. Consumer Electronics: Used in digital TVs, set-top boxes, and gaming consoles.
