SN74HC74QDRQ1

The SN74HC74QDRQ1 is a dual D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is part of the 74HC family, which stands for High-Speed CMOS (Complementary Metal-Oxide-Semiconductor) logic devices. This specific model is designed for high-speed operation and low power consumption, making it suitable for a variety of digital applications.

Key Features:

1. Dual D-Type Flip-Flops: The SN74HC74QDRQ1 contains two independent D-type flip-flops, which can be used to store binary data. Each flip-flop has a data input (D), a clock input (CLK), a set input (SET), a reset input (RESET), and two outputs (Q and Q’).

2. Edge-Triggered: The flip-flops are edge-triggered, meaning they capture the input data on the rising edge of the clock signal. This feature allows for synchronous operation in digital circuits.

3. Asynchronous Set and Reset: The device includes asynchronous set and reset inputs, allowing for immediate control of the output states regardless of the clock signal. This is useful for initializing the flip-flops or forcing them into a known state.

4. High-Speed Operation: The SN74HC74QDRQ1 is capable of operating at high speeds, with propagation delays typically around 15 ns at a supply voltage of 5V. This makes it suitable for high-frequency applications.

5. Wide Supply Voltage Range: The IC operates over a wide supply voltage range, typically from 2V to 6V, making it versatile for various applications.

6. Low Power Consumption: The CMOS technology used in this IC results in low static power consumption, which is beneficial for battery-operated devices.

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

8. Package Type: The SN74HC74QDRQ1 is available in a TSSOP (Thin Shrink Small Outline Package) package, which is compact and suitable for space-constrained applications.

9. Logic Levels: The device is compatible with standard CMOS logic levels, ensuring it can interface with other logic families.
