Functional Features

The SN74HC273DBR is a D-type positive-edge-triggered flip-flop. It has the following functional features:

  • High-speed operation allows for efficient data processing.
  • Low-power consumption makes it suitable for battery-powered devices.
  • Clear input (CLR) allows for resetting the flip-flop to a known state.
  • Clock pulse input (CP) triggers the flip-flop to latch the data inputs.
  • Data inputs (D0-D7) store the desired information.

Advantages and Disadvantages

Advantages of the SN74HC273DBR include:

  • High-speed operation enables quick data processing.
  • Low-power consumption prolongs battery life in portable devices.
  • Clear input allows for easy reset of the flip-flop.
  • Wide supply voltage range provides flexibility in different applications.

  • Limited number of flip-flop outputs (Q0-Q7).
  • Not suitable for applications requiring negative-edge triggering.

Working Principles

The SN74HC273DBR operates based on positive-edge triggering. When a clock pulse is received at the CP pin, the flip-flop latches the data inputs (D0-D7) and stores them in its internal memory. The stored data can then be accessed from the flip-flop outputs (Q0-Q7). The clear input (CLR) can be used to reset the flip-flop to a known state.

Detailed Application Field Plans

The SN74HC273DBR can be used in various applications, including:

  1. Digital counters
  2. Shift registers
  3. Memory units
  4. Data storage systems
  5. Control circuits
