Working Principles

The MC74VHC374MELG is a flip-flop integrated circuit that stores and transfers data. It operates based on the clock signal provided at the CLK pin. When the clock transitions from low to high, the input data is latched and stored in the flip-flop. The stored data is then available at the output pins. The master reset (MR) pin can be used to clear the stored data and set all outputs to a known state.

Detailed Application Field Plans

The MC74VHC374MELG can be used in various digital applications, including but not limited to: - Data storage and transfer in microcontrollers and microprocessors - Address decoding in memory systems - Bus-oriented systems requiring 3-state outputs - Control and synchronization circuits
