SN74LV74APWR

The SN74LV74APWR is a dual D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is part of the 74LV family, which is known for its low-voltage operation and high-speed performance. Here’s a detailed description of its features and specifications:

General Description:

• Type: Dual D-type Flip-Flop
• Package: TSSOP (Thin Shrink Small Outline Package)
• Pin Count: 14 pins
• Supply Voltage: Operates from 2.0V to 5.5V, making it suitable for low-voltage applications.
• Technology: CMOS (Complementary Metal-Oxide-Semiconductor), which provides low power consumption and high noise immunity.

Functional Features:

• D Flip-Flops: The SN74LV74APWR contains two independent D-type flip-flops. Each flip-flop has a data input (D), a clock input (CLK), a set input (SET), a reset input (RESET), and two outputs (Q and Q’).
• Edge-Triggered: The flip-flops are edge-triggered, meaning they capture the input data on the rising edge of the clock signal.
• Asynchronous Set and Reset: The SET and RESET inputs allow for asynchronous control of the flip-flops, enabling them to be set or reset regardless of the clock signal.
• Output States: The outputs (Q and Q’) reflect the state of the input data at the moment of the clock edge, with Q’ being the complement of Q.

Electrical Characteristics:

• Propagation Delay: The typical propagation delay from the clock to the output is around 15 ns at 5V, which allows for high-speed operation in digital circuits.
• Power Consumption: The device features low static and dynamic power consumption, making it ideal for battery-operated devices and energy-efficient applications.
• Input and Output Voltage Levels: The input and output voltage levels are compatible with standard TTL logic levels, ensuring interoperability with other logic families.
