Detailed Pin Configuration

The SN74LVC1G79YEPR has the following pin configuration:

  1. GND (Ground)
  2. D (Data input)
  3. CP (Clock pulse input)
  4. PR (Preset input)
  5. CLR (Clear input)
  6. Q (Flip-flop output)

Functional Features

  • Positive-edge-triggered D-type flip-flop: The flip-flop stores the value of the data input (D) on the rising edge of the clock pulse (CP).
  • Clear and preset inputs: The clear (CLR) input resets the flip-flop to a known state, while the preset (PR) input sets it to another known state.
  • Single-bit storage: The flip-flop can store a single bit of data, which can be either a logic high or a logic low.

Advantages and Disadvantages

Advantages: - Compact size due to SOT-23 package - Wide supply voltage range allows for versatile applications - High clock frequency enables fast operation

Disadvantages: - Limited storage capacity (single bit) - Requires external components for complete circuit implementation

Working Principles

The SN74LVC1G79YEPR is a positive-edge-triggered D-type flip-flop. When the clock pulse (CP) rises from low to high, the value of the data input (D) is captured and stored in the flip-flop. The stored value appears at the output (Q) and remains unchanged until the next rising edge of the clock pulse.

The clear (CLR) input resets the flip-flop to a logic low state, while the preset (PR) input sets it to a logic high state. These inputs allow for initialization or forced states of the flip-flop.

Detailed Application Field Plans

The SN74LVC1G79YEPR can be used in various applications, including but not limited to:

  1. Digital systems: Flip-flops are essential building blocks in digital circuits, used for storing and manipulating binary information.
  2. Counters: Multiple flip-flops can be connected together to create counters, which are widely used in applications such as frequency dividers and event counters.
  3. Memory elements: Flip-flops form the basis of memory elements like registers and shift registers, used for temporary storage and data manipulation.
  4. Clock synchronization: Flip-flops are used to synchronize signals in digital systems, ensuring proper timing and avoiding data corruption.

Detailed and Complete Alternative Models

  1. SN74LVC1G80YEPR: Similar to SN74LVC1G79YEPR, but with an inverted output (Q̅).
  2. SN74LVC1G77YEPR: Single positive-edge-triggered D-type flip-flop without clear and preset inputs.
  3. SN74LVC1G74YEPR: Dual positive-edge-triggered D-type flip-flop with clear and preset inputs.

These alternative models offer similar functionality but may have different pin configurations or additional features to suit specific application requirements.
