Detailed Pin Configuration

The SN74AS174DR has a total of 16 pins, numbered as follows:

  1. CLR (Clear)
  2. D (Data)
  3. CLK (Clock)
  4. Q (Output)
  5. GND (Ground)
  6. Q' (Complementary Output)
  7. PRE (Preset)
  8. VCC (Supply Voltage)

The remaining pins are not used.

Functional Features

The SN74AS174DR is a D-Type Positive-Edge-Triggered Flip-Flop. It stores a single bit of data and can be triggered by a clock signal to update its output. The CLR (Clear) and PRE (Preset) inputs allow for resetting or setting the flip-flop to a specific state. The complementary output Q' provides an inverted version of the output Q.

Advantages and Disadvantages

Advantages: - High-speed operation - Low-power consumption - Compact SOIC package - Versatile functionality with clear and preset inputs

Disadvantages: - Limited operating frequency compared to newer flip-flop models - Not suitable for applications requiring very high-speed operation

Working Principles

The SN74AS174DR operates based on the positive-edge-triggered D-Type Flip-Flop principle. When a rising edge is detected on the CLK (Clock) input, the data present at the D (Data) input is transferred to the Q (Output) and Q' (Complementary Output) pins. The CLR (Clear) and PRE (Preset) inputs can be used to force the output to a specific state.

Detailed Application Field Plans

The SN74AS174DR is commonly used in various digital systems and applications, including:

  1. Register circuits
  2. Counters and dividers
  3. Data storage and transfer systems
  4. Synchronous logic circuits
  5. Control units

Its versatility and reliable performance make it suitable for a wide range of applications that require flip-flop functionality.

Detailed and Complete Alternative Models

  1. SN74LS174N: Similar functionality with TTL-level inputs and outputs.
  2. CD4013BE: Dual D-Type Flip-Flop with complementary outputs.
  3. MC74HC74AN: High-speed CMOS Flip-Flop with preset and clear inputs.

These alternative models offer similar functionality to the SN74AS174DR and can be considered as replacements depending on specific requirements.
