Working Principles

The SN74BCT374NSR is a positive-edge-triggered D-type flip-flop. It stores data at the rising edge of the clock signal. The stored data is then available at the outputs when the output enable (OE) signal is active. The 3-state outputs allow the device to be connected to a shared bus, enabling multiple devices to drive the bus without conflict.

Detailed Application Field Plans

The SN74BCT374NSR can be used in various applications, including but not limited to: - Data storage and transfer in microprocessors and microcontrollers - Address decoding in memory systems - State machine implementation - Bus interface control in communication systems
