SN74HCT273DWG4

The SN74HCT273DWG4 is a high-speed CMOS (Complementary Metal-Oxide-Semiconductor) device from Texas Instruments, specifically designed as an octal D-type flip-flop. This component is part of the HCT (High-speed CMOS TTL-compatible) family, which means it is compatible with TTL (Transistor-Transistor Logic) levels while offering the advantages of CMOS technology, such as lower power consumption and higher noise immunity.

Key Features:

1. Functionality: The SN74HCT273 is an octal D flip-flop, meaning it has eight individual flip-flops that can store one bit of data each. It captures the input data on the rising edge of the clock signal and holds that data until the next clock edge.

2. Input and Output: The device has eight data inputs (D0 to D7) and eight corresponding outputs (Q0 to Q7). Each flip-flop can be independently controlled, allowing for versatile data handling.

3. Clock and Control Signals: The flip-flops are triggered by a clock input (CLK), and there are additional control inputs for setting (SET) and resetting (RESET) the flip-flops. The SET and RESET inputs are asynchronous, meaning they can change the state of the flip-flops regardless of the clock signal.

4. Power Supply: The SN74HCT273 operates over a wide voltage range, typically from 4.5V to 5.5V, making it suitable for various applications. It is designed to work with standard TTL logic levels, ensuring compatibility with other TTL devices.

5. Speed: The device is capable of high-speed operation, with propagation delays typically in the range of nanoseconds, making it suitable for high-frequency applications.

6. Package Type: The "DWG4" designation indicates that the SN74HCT273 is available in a TSSOP (Thin Shrink Small Outline Package) form factor, which is compact and suitable for space-constrained applications. The TSSOP package typically has a small footprint and low profile, making it ideal for modern electronic designs.

7. Temperature Range: The device is rated for operation over a standard industrial temperature range, typically from -40°C to +125°C, ensuring reliability in various environmental conditions.

8. Applications: The SN74HCT273 is commonly used in digital circuits for data storage, state machines, and timing applications. It can be found in consumer electronics, automotive systems, industrial controls, and communication devices.

Electrical Characteristics:

• Input High Voltage (VIH): Typically around 2.0V (minimum) for a logic high.
• Input Low Voltage (VIL): Typically around 0.8V (maximum) for a logic low.
• Output High Voltage (VOH): Typically close to the supply voltage when outputting a high signal.
• Output Low Voltage (VOL): Typically close to ground when outputting a low signal.
• Power Consumption: The device features low static power consumption, making it energy-efficient.

Conclusion:

The SN74HCT273DWG4 is a versatile and efficient octal D flip-flop that combines the benefits of CMOS technology with TTL compatibility. Its high-speed operation, low power consumption, and compact packaging make it an excellent choice for a wide range of digital applications. Whether used in data storage, control systems, or timing circuits, this device provides reliable performance and flexibility for designers and engineers.
