Texas Instruments SN75174DWR

The SN75174DWR is a quad D-type flip-flop designed for use in digital circuit applications. It is commonly used for data storage, buffering, and synchronization of digital signals. The device operates with a logic high and low voltage, making it suitable for interfacing with other digital components. Functions: - D-type Flip-Flop: The core function is to store data based on the state of the D input at the rising edge of the clock signal. - Edge-Triggered: The flip-flops are edge-triggered, meaning they respond only to transitions (rising or falling edges) of the clock signal. - Asynchronous Reset and Set: Features asynchronous reset (active low) and set (active high) inputs, allowing for immediate changes in the output regardless of the clock state. - Buffered Outputs: The device offers buffered outputs, which ensures stable signal levels and minimizes load on previous stages. Applications: - Data Storage: Can be used for temporary data storage in registers. - Signal Synchronization: Ideal for synchronizing data across different clock domains. - Frequency Division: Can be configured to work as a toggle flip-flop for frequency division applications. - Control Systems: Utilized in sequential logic circuits, control systems, and state machines. Alternative Parts: - 74HC74: A popular alternative that offers similar functionality with a higher-speed CMOS technology. - 74LS74: An alternative with lower power consumption but may have reduced speed compared to SN75174. - SN7474: Another related part with similar flip-flop capabilities but with different electrical characteristics. Embedded Modules: - Microcontrollers: The SN75174DWR can be integrated into various microcontroller-based systems for additional data handling. - FPGA/ASIC: Flip-flops like SN75174DWR are also commonly used in FPGAs (Field Programmable Gate Arrays) and ASICs (Application-Specific Integrated Circuits) for custom digital logic designs.
