SN74HCT374NSR

The SN74HCT374NSR is a high-speed, low-power octal D-type flip-flop designed by Texas Instruments. It is part of the HCT (High-speed CMOS TTL-compatible) family, which means it is compatible with TTL logic levels while offering the advantages of CMOS technology, such as lower power consumption and higher noise immunity.

Key Features:

1. Functionality: The SN74HCT374 is an octal D flip-flop, meaning it has eight individual flip-flops that can store one bit of data each. The flip-flops are edge-triggered, capturing the input data on the rising edge of the clock signal.

2. Data Inputs: Each flip-flop has a data input (D) that accepts the data to be stored. The device also features a common clock input (CLK) that synchronizes the operation of all flip-flops.

3. Output: The outputs (Q) are available for each flip-flop, providing the stored data. There are also complementary outputs (Q̅) for each flip-flop, which output the inverse of the stored data.

4. Control Inputs: The device includes a common output enable (OE) input that allows for the control of the output state. When OE is low, the outputs are enabled; when high, the outputs are in a high-impedance state, effectively disconnecting them from the circuit.

5. Power Supply: The SN74HCT374 operates with a supply voltage range of 4.5V to 5.5V, making it suitable for standard digital logic applications.

6. Speed: The device is designed for high-speed operation, with propagation delays typically around 15 ns at a supply voltage of 5V, making it suitable for fast digital circuits.

7. Package Type: The "NSR" suffix indicates that the device is available in a small-outline package (SOIC), which is compact and suitable for surface-mount applications. The typical package dimensions are 3.9 mm x 4.9 mm.

8. Temperature Range: The SN74HCT374 is rated for operation over a temperature range of -40°C to +125°C, making it suitable for a wide variety of applications, including industrial and automotive environments.

Applications:

The SN74HCT374 is commonly used in digital systems for data storage, temporary data holding, and state machine implementations. It is ideal for applications in microcontroller interfacing, data buffering, and as part of larger digital logic circuits.

Summary:

In summary, the SN74HCT374NSR from Texas Instruments is a versatile and efficient octal D flip-flop that combines the benefits of CMOS technology with TTL compatibility. Its high-speed performance, low power consumption, and robust design make it a popular choice for a wide range of digital applications.
