SN74HC74DBRG4

The SN74HC74DBRG4 is a dual D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is part of the 74HC (High-speed CMOS) family, which is known for its high-speed operation and low power consumption. Here’s a detailed description of its features and specifications:

General Description:

• Type: Dual D-type Flip-Flop
• Functionality: The SN74HC74 consists of two independent D-type flip-flops that can be used for data storage and transfer. 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’).

Key Features:

• High-Speed Operation: The device operates at high speeds, making it suitable for fast digital circuits.
• Low Power Consumption: The CMOS technology used in the SN74HC74 allows for low static power consumption, which is beneficial for battery-operated devices.
• Wide Supply Voltage Range: It typically operates with a supply voltage range of 2V to 6V, making it versatile for various applications.
• Input and Output Compatibility: The flip-flops are compatible with standard TTL (Transistor-Transistor Logic) levels, allowing for easy interfacing with other logic families.
• Edge-Triggered: The flip-flops are edge-triggered, meaning they change their output state on the rising or falling edge of the clock signal, depending on the configuration.
• Asynchronous Set and Reset: The device features asynchronous set and reset inputs, allowing for immediate control of the output states regardless of the clock signal.

Pin Configuration:

The SN74HC74DBRG4 typically comes in a 14-pin Dual In-Line Package (DIP) or a surface-mount package. The pin configuration includes:

• Pin 1: Q1 (Output of Flip-Flop 1)
• Pin 2: Q1’ (Inverted Output of Flip-Flop 1)
• Pin 3: D1 (Data Input for Flip-Flop 1)
• Pin 4: CLK1 (Clock Input for Flip-Flop 1)
• Pin 5: CLR1 (Clear/Reset Input for Flip-Flop 1)
• Pin 6: PRE1 (Preset/Set Input for Flip-Flop 1)
• Pin 7: GND (Ground)
• Pin 8: VCC (Supply Voltage)
• Pin 9: PRE2 (Preset/Set Input for Flip-Flop 2)
• Pin 10: CLR2 (Clear/Reset Input for Flip-Flop 2)
• Pin 11: CLK2 (Clock Input for Flip-Flop 2)
• Pin 12: D2 (Data Input for Flip-Flop 2)
• Pin 13: Q2 (Output of Flip-Flop 2)
• Pin 14: Q2’ (Inverted Output of Flip-Flop 2)

Applications:

The SN74HC74DBRG4 is widely used in various digital applications, including:

• Data storage and transfer in digital circuits.
• Frequency division and signal synchronization.
• State machines and counters.
• Memory storage elements in microcontroller and FPGA designs.

Packaging:

The "DBR" in the part number indicates the package type, which is typically a small outline integrated circuit (SOIC) or a similar surface-mount package. The "G4" suffix indicates that the part is lead-free and compliant with RoHS (Restriction of Hazardous Substances) standards.

Conclusion:

The SN74HC74DBRG4 is a versatile and reliable dual D-type flip-flop that is ideal for a wide range of digital applications. Its high-speed performance, low power consumption, and compatibility with other logic families make it a popular choice among engineers and designers in the field of electronics.
