Functional Features

The SN74LVTH273PWG4 is a D-type flip-flop with an 8-bit storage capacity. It operates at low-voltage levels, providing high-speed performance while consuming minimal power. The flip-flop can store data on its inputs and retain it until a clock signal triggers the transfer of data to the outputs. It features an active LOW clear input (CLR) that resets all outputs to a known state when activated. The active LOW output enable input (OE) allows for controlling the output state.

Advantages and Disadvantages

Advantages: - Low-voltage operation enables compatibility with various systems - High-speed performance allows for quick data processing - Low-power consumption reduces energy requirements - Compact TSSOP package offers space-saving benefits - Clear input provides a convenient reset option - Output enable input allows for flexible output control

Disadvantages: - Limited storage capacity of 8 bits - Requires an external clock signal for data transfer

Working Principles

The SN74LVTH273PWG4 operates based on the principles of D-type flip-flops. When the clock signal transitions from LOW to HIGH, the data present at the inputs (D0-D7) is transferred to the corresponding outputs (Q0-Q7). The stored data remains unchanged until the next clock transition occurs. The clear input (CLR) can be used to reset all outputs to a known state, while the output enable input (OE) allows for enabling or disabling the outputs.

Detailed Application Field Plans

The SN74LVTH273PWG4 is widely used in various digital systems and applications, including:

1. Microcontrollers and microprocessors
2. Data storage devices
3. Communication systems
4. Networking equipment
5. Industrial automation
6. Automotive electronics
7. Consumer electronics

Its ability to store and transfer data efficiently makes it suitable for applications that require sequential logic and memory elements.
