Working Principles

The 74ABT374CMTC operates based on the principles of sequential logic. When the clock signal (CP) transitions from low to high (rising edge), the input data (D0-D7) is latched and stored in the flip-flops. The stored data is then available at the corresponding output pins (Q0-Q7). The output enable (OE) pin controls whether the outputs are active or in a high-impedance state.

Application Field Plans

The 74ABT374CMTC finds extensive use in various digital systems, including but not limited to: - Microprocessors and microcontrollers - Memory systems (RAM, ROM) - Communication devices (routers, switches) - Data storage systems - Industrial automation equipment
