SN74LVC74APWR

The SN74LVC74APWR 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 applications while maintaining high-speed performance. 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 digital circuits.

Functional Characteristics:

• Inputs: Each flip-flop has a D (data) input, a clock input (CLK), and a clear input (CLR). The clear input is asynchronous, meaning it can reset the flip-flop regardless of the clock state.
• Outputs: Each flip-flop has a Q output and a complementary Q' output, providing both the normal and inverted states of the stored data.
• Edge-Triggered: The flip-flops are edge-triggered, meaning they capture the input data on the rising edge of the clock signal, ensuring reliable data storage and transfer.

Performance Specifications:

• Propagation Delay: The typical propagation delay from the clock input to the output 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.
• Temperature Range: The operating temperature range is from -40°C to +125°C, making it suitable for industrial and automotive applications.
