SN74LS74ANSR

The SN74LS74ANSR is a dual D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments, part of the 74LS (Low Power Schottky) series. This IC is designed for use in digital circuits and is commonly utilized for data storage, synchronization, and control applications.

Key Features:

1. Dual D-Type Flip-Flops: The SN74LS74ANSR contains two independent D-type flip-flops, which means it can store two bits of 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. Low Power Consumption: As part of the LS series, this IC is designed to operate with lower power consumption compared to standard TTL (Transistor-Transistor Logic) devices, making it suitable for battery-operated and energy-efficient applications.

3. High Speed: The SN74LS74ANSR offers fast switching times, typically around 15 nanoseconds, allowing it to operate effectively in high-speed digital circuits.

4. TTL Compatible: The device is compatible with TTL logic levels, which means it can interface with other TTL devices without the need for additional level-shifting components.

5. Set and Reset Functionality: The flip-flops can be asynchronously set or reset, allowing for immediate control of the output states regardless of the clock signal. This feature is useful for initializing the state of the flip-flops in a circuit.

6. Pin Configuration: The SN74LS74ANSR is available in a 14-pin Dual In-Line Package (DIP) or surface-mount configurations. The pins are arranged in a standard layout, with specific pins designated for power (Vcc), ground (GND), data inputs, clock inputs, and outputs.

7. Operating Voltage: The device typically operates at a supply voltage of 4.75V to 5.25V, making it suitable for standard digital logic applications.

8. Temperature Range: The SN74LS74ANSR is rated for operation over a temperature range of 0°C to 70°C, making it suitable for commercial applications.

Applications:

• Data Storage: Used in registers and memory applications where temporary data storage is required.
• Frequency Division: Can be used in frequency dividers and counters in digital circuits.
• State Machines: Useful in designing finite state machines where the state needs to be stored and transitioned based on input signals.
• Control Circuits: Employed in control logic for various electronic devices and systems.

Conclusion:

The SN74LS74ANSR is a versatile and reliable dual D-type flip-flop that is widely used in digital electronics. Its combination of low power consumption, high speed, and TTL compatibility makes it an excellent choice for a variety of applications in both consumer and industrial electronics.
