SN74HC563DWR

The SN74HC563DWR is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) quad D-type flip-flop integrated circuit produced by Texas Instruments. It is part of the 74HC family, which is known for its high-speed performance and low power consumption, making it suitable for a variety of digital applications.

Key Features:

1. Functionality: The SN74HC563DWR contains four independent D-type flip-flops. Each flip-flop has a data input (D), a clock input (CLK), a clear input (CLR), and a complementary output (Q and Q̅). The flip-flops are edge-triggered, meaning they capture the input data on the rising edge of the clock signal.

2. Power Supply: The device operates over a wide voltage range, typically from 2V to 6V, allowing it to be used in various electronic systems. It is designed to work with standard TTL (Transistor-Transistor Logic) levels.

3. Speed: The SN74HC563DWR is capable of high-speed operation, with propagation delays typically around 15 ns at 5V, making it suitable for high-frequency applications.

4. Logic Levels: The device is compatible with standard logic levels, ensuring it can interface with other TTL and CMOS devices without issues.

5. Clear Functionality: The clear (CLR) input allows for asynchronous resetting of the flip-flops, setting the output Q to low (0) regardless of the clock or data inputs. This feature is useful for initializing the state of the flip-flops in digital circuits.

6. Package Type: The SN74HC563DWR is available in a TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications. The package typically has 16 pins, allowing for easy integration into printed circuit boards (PCBs).

7. Temperature Range: The device is rated for operation over a standard temperature range, making it suitable for a variety of environments.

8. Applications: The SN74HC563DWR is commonly used in digital systems for data storage, state machines, counters, and other applications where data needs to be latched or stored temporarily.

Electrical Characteristics:

• Input Voltage Levels: The input high voltage (VIH) and input low voltage (VIL) levels are defined to ensure proper operation within the specified supply voltage range.
• Output Drive Capability: The outputs can typically drive standard TTL loads, making it versatile for interfacing with other components.

Conclusion:

The SN74HC563DWR is a versatile and efficient quad D-type flip-flop that provides reliable performance in digital circuits. Its combination of high speed, low power consumption, and ease of integration makes it a popular choice for engineers and designers working on various electronic projects. Whether used in simple applications or complex digital systems, the SN74HC563DWR offers a robust solution for data storage and manipulation.
