Working Principles

The 74VHCT374AMTC operates as an octal D-type flip-flop, storing and transferring data based on the clock input. When the clock signal transitions from low to high (positive edge), the data inputs are latched and stored in the flip-flop's internal memory. The stored data is then available at the corresponding output pins. The asynchronous clear input allows for resetting the flip-flop, while the output enable input enables or disables the outputs.

Detailed Application Field Plans

The 74VHCT374AMTC finds applications in various digital systems, including but not limited to: - Microcontrollers - Data storage devices - Communication systems - Industrial automation - Automotive electronics
