Functional Features

  • The SN74LVTH273DWRE4 is a positive-edge-triggered D-type flip-flop.
  • It has an asynchronous clear input (CLR) to reset the flip-flop.
  • The output enable input (OE) allows for the tri-state outputs, enabling multiple devices to be connected together.

Advantages and Disadvantages

Advantages: - Low-voltage operation makes it suitable for battery-powered applications. - High-speed operation allows for efficient data transfer. - Tri-state outputs provide flexibility in connecting multiple devices.

Disadvantages: - Limited operating temperature range (-40°C to 85°C). - Requires external components for proper functioning.

Working Principles

The SN74LVTH273DWRE4 operates based on positive-edge triggering. When a rising edge is detected on the clock input (not mentioned in specifications), the data present at the D inputs is transferred to the corresponding Q outputs. The outputs remain unchanged when the clock is low or during the setup and hold time requirements.
