SN74HC563DW

The SN74HC563DW is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) device from Texas Instruments, specifically designed as a quad D-type flip-flop. This component is part of the 74HC family, which is known for its high-speed operation and low power consumption, making it suitable for a variety of digital applications.

Key Features:

1. Functionality: The SN74HC563DW 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. Operating Voltage: The device operates over a wide voltage range, typically from 2V to 6V, making it compatible with various logic levels.

3. Speed: The SN74HC563DW is designed for high-speed operation, with propagation delays typically around 15 ns at 5V, allowing for fast data processing in digital circuits.

4. Power Consumption: As a CMOS device, it features low static power consumption, which is advantageous for battery-operated devices and applications where power efficiency is critical.

5. Package Type: The "DW" suffix indicates that the SN74HC563 is available in a TSSOP (Thin Shrink Small Outline Package) package, which is compact and suitable for surface-mount technology (SMT). This package typically has 16 pins, allowing for a small footprint on printed circuit boards (PCBs).

6. Input/Output Characteristics: The flip-flops have high noise immunity and can accept standard TTL (Transistor-Transistor Logic) input levels. The outputs are capable of driving standard TTL loads.

7. Clear Functionality: The clear (CLR) input allows for asynchronous resetting of the flip-flops, setting the output Q to a low state regardless of the clock or data inputs.

8. Applications: The SN74HC563DW is widely used in various applications, including data storage, shift registers, frequency dividers, and as part of larger digital systems in computers, communication devices, and consumer electronics.

Electrical Characteristics:

• Supply Voltage (Vcc): 2V to 6V
• Input Voltage (Vi): 0V to Vcc
• Output Voltage (Vo): 0V to Vcc
• Propagation Delay (tpd): Typically 15 ns at 5V
• Power Dissipation: Low, typically in the micro-watt range

Conclusion:

The SN74HC563DW is a versatile and efficient quad D-type flip-flop that provides reliable performance in a compact package. Its combination of high speed, low power consumption, and flexible operating voltage makes it an excellent choice for a wide range of digital applications. Whether used in simple logic circuits or complex digital systems, the SN74HC563DW is a valuable component for engineers and designers.
