SN74HCT273NSR

The SN74HCT273NSR 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 SN74HCT273NSR contains eight D-type flip-flops, which are used for data storage and transfer. Each flip-flop has a data input (D), a clock input (CLK), and an output (Q). The flip-flops capture the input data on the rising edge of the clock signal.

2. Pin Configuration: The device is typically available in a 20-pin surface-mount package (SOIC), which allows for easy integration into various circuit designs. The pins are arranged to provide access to the data inputs, clock inputs, outputs, and control signals.

3. Power Supply: The SN74HCT273 operates with a supply voltage range of 4.5V to 5.5V, making it suitable for standard digital logic applications. It is designed to work with a wide range of power supply voltages, ensuring compatibility with various systems.

4. Speed: The device is capable of operating at high speeds, with a maximum propagation delay of around 15 ns at a supply voltage of 5V. This makes it suitable for applications requiring fast data processing and storage.

5. Logic Levels: The HCT family is designed to be compatible with TTL logic levels, meaning that it can interface directly with TTL devices without the need for additional level-shifting components.

6. Control Inputs: The SN74HCT273 includes asynchronous set (SET) and reset (RESET) inputs, allowing for immediate control of the output states regardless of the clock signal. This feature is useful for initializing the flip-flops to a known state.

7. Temperature Range: The device is rated for operation over a temperature range of -40°C to +125°C, making it suitable for both commercial and industrial applications.

8. Applications: Common applications for the SN74HCT273 include data storage, shift registers, counters, and other digital logic circuits where temporary data holding is required.

Summary:

The SN74HCT273NSR from Texas Instruments is a versatile and reliable octal D-type flip-flop that combines the benefits of CMOS technology with TTL compatibility. Its high-speed operation, low power consumption, and robust performance make it an ideal choice for a wide range of digital applications in both consumer and industrial electronics.
