Functional Features

• Octal D-type flip-flop with clear functionality
• Positive-edge triggered clock input (CLK)
• Asynchronous active LOW clear input (CLR)
• 3-state outputs for bus-oriented applications
• Low power consumption
• High noise immunity

Advantages and Disadvantages

Advantages: - Wide supply voltage range allows compatibility with various systems - Clear functionality provides flexibility in controlling the flip-flop state - 3-state outputs enable efficient bus sharing

Disadvantages: - Limited number of flip-flops in a single package (8 in this case) - Not suitable for high-speed applications due to its relatively low maximum operating frequency

Working Principles

The 74LV273DB,112 is an octal D-type flip-flop with clear. It stores data based on the positive edge of the clock signal (CLK). The clear input (CLR) asynchronously resets all flip-flops to a cleared state when activated. The stored data can be accessed through the Q0-Q7 outputs.

Detailed Application Field Plans

The 74LV273DB,112 is commonly used in digital systems where the storage and retrieval of data are required. Some specific application fields include: - Microcontrollers - Data storage devices - Communication systems - Industrial automation

Detailed and Complete Alternative Models

Some alternative models that provide similar functionality to the 74LV273DB,112 are: - 74HC273: High-speed CMOS version - CD4013: Dual D-type flip-flop with clear - SN74LS273: Low-power Schottky version
