74HC574PW,112

The 74HC574PW,112 is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) octal D-type flip-flop with a 3-state output, manufactured by Nexperia. This device is part of the 74HC (High-speed CMOS) series, which is known for its low power consumption and high-speed operation, making it suitable for a variety of digital applications.

Key Features:

1. Functionality: The 74HC574 is an octal flip-flop, meaning it contains eight individual D-type flip-flops. Each flip-flop can store one bit of data. The device captures the value of the D input on the rising edge of the clock signal (CLK) and holds that value until the next clock edge.

2. 3-State Outputs: The outputs of the flip-flops can be placed in a high-impedance state, allowing multiple devices to share the same output line without interference. This is controlled by the output enable (OE) pin.

3. Input and Output Configuration: The device has a total of 8 data inputs (D0 to D7), 8 outputs (Q0 to Q7), a clock input (CLK), an output enable input (OE), and a reset input (CLR). The reset input allows for asynchronous clearing of all flip-flops, setting their outputs to a low state.

4. Supply Voltage: The 74HC574 operates over a wide supply voltage range, typically from 2V to 6V, making it compatible with various logic levels.

5. Speed: The device is designed for high-speed operation, with propagation delays typically in the range of nanoseconds, allowing for fast data processing in digital circuits.

6. Temperature Range: The 74HC574 is rated for operation in a standard temperature range, making it suitable for most commercial applications.

7. Package Type: The "PW" in the part number indicates that the device is packaged in a TSSOP (Thin Shrink Small Outline Package) format, which is compact and suitable for surface-mount technology (SMT). This package type is ideal for applications where space is a constraint.

8. Pin Configuration: The device features a specific pin layout that includes power supply pins (VCC and GND), data inputs, clock input, output enable, and reset. The pin configuration is designed for easy integration into digital circuits.

Applications:

The 74HC574 is widely used in various applications, including:

• Data storage and transfer in digital systems.
• Shift registers and data latches.
• Temporary data holding in microcontroller interfacing.
• State machines and control logic in digital circuits.
• Any application requiring reliable data synchronization and storage.

Conclusion:

The 74HC574PW,112 from Nexperia is a versatile and efficient octal D-type flip-flop that provides essential functionality for digital circuit design. Its combination of high-speed operation, low power consumption, and flexible output control makes it a popular choice for engineers and designers working on a wide range of electronic projects.
