SN74F112D

The SN74F112D is a dual J-K flip-flop integrated circuit (IC) manufactured by Texas Instruments. It is part of the 74F series, which is known for its high-speed performance and low power consumption. The SN74F112D is designed for use in digital circuits where data storage and manipulation are required.

Key Features:

1. Dual J-K Flip-Flops: The SN74F112D contains two independent J-K flip-flops, which can be used to store one bit of data each. The J-K flip-flop is a versatile type of flip-flop that can toggle its output based on the inputs J (set) and K (reset).

2. Edge-Triggered: The flip-flops are edge-triggered, meaning they change their output state on the rising or falling edge of the clock signal. This feature allows for precise timing in digital circuits.

3. Asynchronous Set and Reset: Each flip-flop has 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 to a known state.

4. High-Speed Operation: The SN74F112D is designed for high-speed applications, with a typical propagation delay of around 3.5 ns at a supply voltage of 5V. This makes it suitable for use in fast digital systems.

5. Low Power Consumption: The device operates with a low supply current, making it energy-efficient and suitable for battery-powered applications.

6. Wide Supply Voltage Range: The SN74F112D can operate over a supply voltage range of 4.5V to 5.5V, providing flexibility in various circuit designs.

7. TTL Compatible: The device is compatible with TTL (Transistor-Transistor Logic) levels, allowing it to interface easily with other TTL logic devices.

8. Package Type: The SN74F112D is typically available in a 14-pin DIP (Dual In-line Package) or other surface-mount packages, making it easy to integrate into various circuit layouts.

Applications:

The SN74F112D is commonly used in a variety of digital applications, including:

• Data Storage: Used in registers and memory devices to store binary data.
