SN74LS75DG4

The SN74LS75DG4 is a dual D-type flip-flop integrated circuit (IC) manufactured by Texas Instruments, part of the 74LS (Low Power Schottky) series. This device 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 SN74LS75 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), and an output (Q).

2. Low Power Consumption: As part of the LS series, the SN74LS75 is designed to operate with low power consumption, making it suitable for battery-operated devices and applications where power efficiency is critical.

3. Schottky Transistor Technology: The use of Schottky transistor technology allows for faster switching speeds compared to standard TTL (Transistor-Transistor Logic) devices, which enhances performance in high-speed applications.

4. Edge-Triggered Operation: The flip-flops are edge-triggered, meaning they capture the input data on the rising or falling edge of the clock signal, providing reliable data storage and transfer.

5. Asynchronous Set and Reset: Each flip-flop features asynchronous set (S) and reset (R) inputs, allowing for immediate control of the output state regardless of the clock signal. This is useful for initializing the flip-flops or forcing them into a known state.

6. TTL Compatible: The SN74LS75 is compatible with TTL logic levels, making it easy to integrate into existing TTL-based systems.

7. Wide Supply Voltage Range: The device typically operates within a supply voltage range of 4.75V to 5.25V, which is standard for TTL logic devices.

8. Temperature Range: The SN74LS75 is designed to operate over a temperature range of -40°C to +85°C, making it suitable for industrial and automotive applications.

Pin Configuration:

The SN74LS75 is typically housed in a 14-pin dual in-line package (DIP) or surface-mount package. The pin configuration includes:

• Inputs: D1, D2 (data inputs for the two flip-flops), CLK1, CLK2 (clock inputs), S1, S2 (set inputs), R1, R2 (reset inputs).
• Outputs: Q1, Q2 (outputs for the two flip-flops), and their complementary outputs Q1' and Q2'.

Applications:

The SN74LS75 is widely used in various applications, including:

• Data storage and transfer in digital systems.
• Frequency division and counting applications.
• State machines and control logic circuits.
• Temporary data holding in microcontroller interfacing.

Conclusion:

The SN74LS75DG4 from Texas Instruments is a versatile and reliable dual D-type flip-flop that combines low power consumption with high-speed performance, making it an excellent choice for a wide range of digital applications. Its features, such as asynchronous set/reset and TTL compatibility, enhance its usability in both simple and complex electronic designs.
