Specifications

The SN74LV74APWRE4 is a low-voltage, dual D-type positive-edge-triggered flip-flop integrated circuit. It operates at a voltage range of 1.65V to 5.5V, making it suitable for various low-power applications. The flip-flop has two independent data inputs (D0 and D1), each with its own clock input (CLK0 and CLK1). The outputs (Q0 and Q1) provide the state of the flip-flop based on the input data and clock signals.

Detailed Pin Configuration

The SN74LV74APWRE4 has a total of 14 pins, which are assigned specific functions as follows:

  • Pin 1: CLK0 - Clock input for the first flip-flop
  • Pin 2: D0 - Data input for the first flip-flop
  • Pin 3: CLR0 - Clear input for the first flip-flop
  • Pin 4: PR0 - Preset input for the first flip-flop
  • Pin 5: Q0 - Output for the first flip-flop
  • Pin 6: GND - Ground reference
  • Pin 7: Q1 - Output for the second flip-flop
  • Pin 8: Q1 - Output for the second flip-flop
  • Pin 9: PR1 - Preset input for the second flip-flop
  • Pin 10: CLR1 - Clear input for the second flip-flop
  • Pin 11: D1 - Data input for the second flip-flop
  • Pin 12: CLK1 - Clock input for the second flip-flop
  • Pin 13: VCC - Positive power supply
  • Pin 14: GND - Ground reference

Functional Features

The SN74LV74APWRE4 offers several functional features that make it a versatile flip-flop solution. It operates on positive-edge-triggered clock inputs, allowing for precise timing control. The dual flip-flop design enables independent operation of two separate data inputs and clock signals. The clear (CLR) and preset (PR) inputs provide additional control over the flip-flop's state. The low-voltage operation range makes it suitable for battery-powered devices and other low-power applications.

Advantages and Disadvantages

Advantages: - Low-voltage operation range allows for compatibility with various systems - Dual flip-flop design provides flexibility in handling multiple data inputs - Positive-edge-triggered clock inputs ensure accurate timing control - Compact TSSOP package saves board space

Disadvantages: - Limited to positive-edge-triggered operation only - Not suitable for high-voltage applications

Working Principles

The SN74LV74APWRE4 operates based on the principles of positive-edge-triggered flip-flops. When a rising edge is detected on the clock input, the data at the corresponding D input is transferred to the Q output. The clear (CLR) and preset (PR) inputs allow for resetting or setting the flip-flop's state, respectively. The low-voltage operation ensures reliable performance even in low-power scenarios.

Detailed Application Field Plans

The SN74LV74APWRE4 finds applications in various fields where reliable flip-flop functionality is required. Some potential application areas include:

  1. Digital Communication Systems: The flip-flop can be used for synchronization and data storage in digital communication systems, ensuring accurate transmission of information.
