SN74AUC1G74DCUR

The SN74AUC1G74DCUR is a single D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is part of the AUC family of logic devices, which are designed for low-voltage operation and high-speed performance. Here’s a detailed description of its features and specifications:

General Description:

• Type: D-type Flip-Flop
• Functionality: The SN74AUC1G74 is used to store a single bit of data. It captures the value of the D (data) input at a specific moment defined by the clock input (CLK) and holds that value until the next clock edge.

Key Features:

• Supply Voltage: The device operates over a wide supply voltage range, typically from 0.8V to 3.6V, making it suitable for low-power applications.
• Input Voltage Levels: It is compatible with both standard and low-voltage logic levels, allowing it to interface with various digital circuits.
• Propagation Delay: The flip-flop has a low propagation delay, typically around 3.5 ns at 3.3V, which enables high-speed operation.
• Power Consumption: The SN74AUC1G74 is designed for low power consumption, making it ideal for battery-operated devices and energy-efficient applications.
• Output Drive Capability: It can drive up to 8 mA of output current, allowing it to interface with other logic devices or loads directly.

Pin Configuration:

• The SN74AUC1G74 is available in a small SOT-23 package, which is compact and suitable for space-constrained applications. The typical pin configuration includes:
  • D (Data Input): The input where the data to be stored is applied.
  • CLK (Clock Input): The input that triggers the flip-flop to capture the data from the D input.
  • Q (Output): The output that reflects the stored data.
  • Q' (Inverted Output): The complementary output, which is the inverse of the Q output.
  • Set and Reset Inputs: These may be included in some configurations to asynchronously set or reset the flip-flop.

Applications:

• The SN74AUC1G74 is widely used in digital circuits for data storage, state machines, and timing applications. It is suitable for use in:
  • Microcontroller interfacing
  • Data buffering
  • Frequency division
  • Shift registers
  • Memory applications

Packaging:

• The device is typically available in a SOT-23 package, which is a small, surface-mount package that allows for easy integration into compact circuit designs.

Conclusion:

The SN74AUC1G74DCUR from Texas Instruments is a versatile and efficient D-type flip-flop that provides reliable data storage and processing capabilities in low-voltage digital applications. Its combination of low power consumption, high-speed performance, and compact packaging makes it an excellent choice for modern electronic designs.
