Product Description
The HD74LS76 is a dual J-K flip-flop integrated circuit (IC) belonging to the Low Power Schottky (LS) logic family. It is similar to the SN74LS76 from Texas Instruments, offering improved performance with reduced power consumption compared to standard TTL ICs.
Key Features:
- Dual J-K Flip-Flops: The IC contains two independent J-K flip-flops, ideal for storing binary data and managing sequential operations in digital systems.
- Positive Edge-Triggered: The flip-flops change state on the rising edge of the clock signal, ensuring that the data is updated synchronously with the clock.
- Master-Slave Configuration: Each flip-flop is arranged in a master-slave configuration, meaning the master latch holds the input value during the clock pulse, and the slave latch holds the output.
- Asynchronous Reset and Set: Each flip-flop has individual asynchronous reset (clear) and set inputs for independent control over the flip-flop outputs, enabling precise control in various applications.
- Low Power Consumption: The LS series ensures low power operation, making it suitable for power-sensitive designs.
- TTL Compatibility: The IC is fully compatible with standard TTL logic levels and operates at a supply voltage of 5V.
Applications:
- Data Storage: Used in memory devices, shift registers, and counters where data needs to be stored or manipulated.
- Timing and Sequencing Circuits: Essential for applications that require edge-triggered operations and synchronization, such as pulse generators and state machines.
- Control Systems: Often used in control circuits, such as those that require clocked data storage or sequential control.
Pin Configuration:
- Inputs: J (data input), K (data input), Clock, Reset, and Set for each flip-flop.
- Outputs: Q (output) and Q' (inverted output) for each flip-flop.
The HD74LS76 is designed for use in digital systems where reliable binary data storage and control are required, and it is ideal for applications needing two independent flip-flops in a single package. It provides an efficient solution for timing, data storage, and sequencing in TTL-compatible systems.
