SN74LVC74APW

The SN74LVC74APW is a dual D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is part of the LVC (Low-Voltage CMOS) family, which is designed for low power consumption and high-speed operation. Here’s a detailed description of its features and specifications:

General Features:

• Type: Dual D-type Flip-Flop
• Package: TSSOP (Thin Shrink Small Outline Package), specifically in a 14-pin configuration.
• Supply Voltage: Operates within a voltage range of 1.65V to 5.5V, making it suitable for a variety of low-voltage applications.
• Logic Levels: Compatible with both TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor) logic levels, allowing for versatile interfacing with other logic families.

Functional Characteristics:

• Inputs: Each flip-flop has a D (data) input, a clock input (CLK), and a clear input (CLR). The D input is where the data is fed into the flip-flop.
• Outputs: Each flip-flop has a Q output and a complementary Q' output, which provides the inverted state of the Q output.
• Edge-Triggered: The flip-flops are edge-triggered, meaning they capture the input data on the rising edge of the clock signal.
• Asynchronous Clear: The clear input allows for asynchronous resetting of the flip-flops, setting the Q output to low (0) regardless of the clock state.

Electrical Characteristics:

• Propagation Delay: The typical propagation delay from the clock edge to the output change is around 3.5 ns at a supply voltage of 3.3V, making it suitable for high-speed applications.
• Power Consumption: The device is designed for low power consumption, with a typical supply current of only a few microamperes, which is beneficial for battery-operated devices.
• Input/Output Voltage Levels: The input high voltage (VIH) and input low voltage (VIL) thresholds are defined to ensure reliable operation across the specified voltage range.

Applications:

The SN74LVC74APW is widely used in various applications, including:

• Data storage and transfer in digital circuits.
• Frequency division and signal synchronization.
• State machines and control logic in embedded systems.
• Temporary data storage in microcontroller applications.

Pin Configuration:

The 14-pin TSSOP package includes:

• Pins for the two D flip-flops (D1, D2, CLK1, CLK2, CLR1, CLR2).
• Output pins (Q1, Q2, Q'1, Q'2).
• Power supply (VCC) and ground (GND) pins.

Conclusion:

The SN74LVC74APW is a versatile and efficient dual D-type flip-flop that provides reliable performance in a compact package. Its low voltage operation, low power consumption, and compatibility with various logic families make it an excellent choice for modern digital circuit designs.
