SN74HCT374PWR

The SN74HCT374PWR 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 SN74HCT374PWR contains eight D-type flip-flops with individual data inputs (D0 to D7) and a common clock input (CLK). The flip-flops capture the data on the rising edge of the clock signal, making it suitable for synchronous applications.

2. Output Configuration: Each flip-flop has a complementary output (Q and Q̅), allowing for both the stored value and its inverse to be accessed. This feature is useful in various digital logic applications.

3. Control Inputs: The device includes a master reset (MR) input that can asynchronously reset all flip-flops to a low state, providing flexibility in controlling the state of the outputs.

4. Power Supply: The SN74HCT374PWR operates with a supply voltage range of 4.5V to 5.5V, making it compatible with standard TTL and CMOS logic levels.

5. Speed: With a maximum propagation delay of around 15 ns at 5V, the SN74HCT374PWR is suitable for high-speed applications, allowing for efficient data processing in digital circuits.

6. Package Type: The device is available in a TSSOP (Thin Shrink Small Outline Package) with a 20-pin configuration, which is compact and suitable for space-constrained applications.

7. Temperature Range: The SN74HCT374PWR is rated for operation over a temperature range of -40°C to 125°C, making it suitable for industrial and automotive applications.

8. Applications: Common applications include data storage, shift registers, and temporary data holding in digital systems. It is often used in microcontroller interfacing, digital signal processing, and other logic circuit designs.

Electrical Characteristics:

• Input High Voltage (VIH): Typically around 2.0V (minimum) for reliable high-level recognition.
• Input Low Voltage (VIL): Typically around 0.8V (maximum) for reliable low-level recognition.
• Output High Voltage (VOH): Typically close to VCC when the output is high.
• Output Low Voltage (VOL): Typically close to ground when the output is low.

Summary:

The SN74HCT374PWR is a versatile and efficient octal D-type flip-flop that combines the benefits of CMOS technology with TTL compatibility. Its features make it an excellent choice for a wide range of digital applications, providing reliable performance in both consumer and industrial electronics.
