Working Principles
The 74ACT374MTC is a positive-edge-triggered flip-flop that stores data on the rising edge of the clock signal. When the master reset (MR) input is low, the flip-flop is enabled, and the data inputs (D0-D7) are transferred to the corresponding Q outputs (Q0-Q7). The output enable (OE) input controls the 3-state outputs, allowing them to be either active or in a high-impedance state.
Detailed Application Field Plans
The 74ACT374MTC is widely used in various digital systems where data storage and retrieval are required. Some common application fields include: - Microprocessors and microcontrollers - Data communication systems - Memory modules - Industrial automation equipment - Automotive electronics
