• Positive-edge triggered clock input (CP)
• Asynchronous active LOW clear input (CLR)
• 3-state outputs for bus-oriented applications
• High noise immunity due to hysteresis on inputs

Advantages and Disadvantages

Advantages: - Low-voltage operation allows for compatibility with a wide range of systems - Clear functionality provides flexibility in controlling the output state - 3-state outputs enable easy integration into bus-oriented applications - High noise immunity ensures reliable operation in noisy environments

Disadvantages: - Limited maximum operating frequency compared to some other ICs - Only available in SOIC package, which may not be suitable for all applications

Working Principles

The 74LV377D,112 is an octal D-type flip-flop with clear functionality. It operates based on positive-edge triggered clock input (CP) and asynchronous active LOW clear input (CLR). The flip-flop stores data at the input (D0-D7) when a rising edge is detected on the clock input. The stored data is then available at the corresponding output (Q0-Q7). The clear input allows for resetting the flip-flop to a known state.

Detailed Application Field Plans

The 74LV377D,112 can be used in various digital logic applications, including but not limited to: - Register and counter circuits - Data storage and retrieval systems - Address decoding and selection - Bus interface control
