SN74LV175APWR

The SN74LV175APWR is a quad D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is designed for use in digital circuits and 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 Features:

• Type: Quad D-type Flip-Flop
• Technology: Low-Voltage CMOS (LV)
• Package: TSSOP (Thin Shrink Small Outline Package), specifically in a 20-pin configuration.
• Operating Voltage: Typically operates from 2.0V to 5.5V, making it suitable for battery-powered applications and low-voltage systems.
• Propagation Delay: Fast switching times, with a typical propagation delay of around 5 ns at 5V, allowing for high-speed data processing.

Functional Description:

• Inputs and Outputs: The SN74LV175APWR contains four independent D-type flip-flops. Each flip-flop has a data input (D), a clock input (CLK), a clear input (CLR), and an output (Q). The outputs are complemented (Q’).
• Operation: On the rising edge of the clock signal, the data present at the D input is transferred to the Q output. The flip-flops can be cleared asynchronously using the CLR input, which sets the Q output to low regardless of the clock state.
• Edge-Triggered: The flip-flops are edge-triggered, meaning they respond to changes in the clock signal only on a specific edge (rising edge in this case).

Electrical Characteristics:

• Input High Voltage (VIH): Minimum of 1.5V for a 3.3V supply, ensuring reliable logic high detection.
• Input Low Voltage (VIL): Maximum of 0.8V for a 3.3V supply, ensuring reliable logic low detection.
• Output Drive Capability: Capable of driving standard CMOS loads, with a typical output current of ±24 mA.
• Power Consumption: Low static power consumption, making it suitable for energy-efficient designs.

Applications:

• Data Storage: Used in applications requiring temporary data storage, such as registers and buffers.
• State Machines: Ideal for implementing state machines in digital logic designs.
• Timing Circuits: Can be used in timing applications where synchronization of data is crucial.

Additional Information:

• Thermal Characteristics: The TSSOP package provides good thermal performance, allowing for efficient heat dissipation.
• Pin Configuration: The 20-pin TSSOP package has a specific pin layout that includes power supply pins (VCC and GND), data inputs, clock inputs, clear inputs, and output pins for each flip-flop.

Conclusion:

The SN74LV175APWR is a versatile and efficient quad D-type flip-flop that is well-suited for a variety of digital applications, particularly in low-voltage environments. Its combination of high-speed operation, low power consumption, and ease of integration makes it a popular choice among engineers and designers in the field of electronics.
