Functional Features

The 74LVQ273SJX is a D-type flip-flop with eight individual flip-flops integrated into a single IC. It can store and manipulate binary data, making it suitable for applications such as data storage, counters, and registers.

The IC features a clock input (CP) that controls the timing of data storage and retrieval. The output enable (OE) pin allows for enabling or disabling the outputs, providing flexibility in data processing.

Advantages and Disadvantages

Advantages

• Low-voltage operation allows for compatibility with modern digital systems.
• High-speed performance enables efficient data processing in high-frequency applications.
• Compact SOP package provides protection and ease of handling.

Disadvantages

• Limited number of flip-flops may restrict its use in complex applications requiring more storage capacity.
• Requires external components for complete functionality, such as clock signals and power supply.

Working Principles

The 74LVQ273SJX operates based on the principles of sequential logic. When the clock input (CP) receives a rising edge, the data present at the inputs (D0-D7) is latched and stored in the corresponding flip-flops. The stored data can then be accessed from the outputs (Q0-Q7).

The output enable (OE) pin controls whether the stored data is visible at the outputs. When OE is low, the outputs are enabled, allowing the stored data to be read. Conversely, when OE is high, the outputs are disabled, isolating the flip-flops from the external circuitry.

Detailed Application Field Plans

The 74LVQ273SJX can be used in various applications, including:

1. Data storage: The IC can be employed to store binary data in microcontrollers, memory systems, and communication devices.
2. Counters: It can be utilized as a building block for designing digital counters used in frequency dividers, timers, and event counters.
3. Registers: The IC is suitable for implementing shift registers, parallel-in-serial-out (PISO) or serial-in-parallel-out (SIPO) registers.
