74LS76 Dual JK Flip Flop with Set and Clear IC Hitachi (7476) DIP 16 Package

74LS76 Dual JK Flip Flop with Set and Clear IC Hitachi (7476) DIP 16 Package

The 74LS76 is a Dual JK Flip-Flop with Set (Preset) and Clear inputs, designed using Low Power Schottky TTL technology for high speed and low power consumption.

Each flip-flop features:

• Independent J, K, Clock (CLK), Preset (PRE?), and Clear (CLR?) inputs.
• Complementary outputs (Q and Q?).
• Edge-triggered operation — outputs change on the negative edge (falling edge) of the clock signal.
• Asynchronous Preset and Clear, which override the clock and J/K inputs when activated.

This IC is widely used in frequency dividers, toggle flip-flops, binary counters, data storage, and control logic circuits.

Functional Description

Each JK flip-flop in the 74LS76 acts as a universal bistable device capable of storing 1 bit of information.
The Preset (PRE?) and Clear (CLR?) inputs are asynchronous and can override clock and data inputs to immediately set or reset the flip-flop.

The outputs Q and Q? always remain complementary. When both J and K are HIGH, the flip-flop toggles its output on each falling edge of the clock signal — making it suitable for frequency division.

Applications

• Toggle Flip-Flop / T-Flip-Flop
• Frequency Divider (Divide-by-2 circuit)
• Binary Counters and Registers
• Pulse and Signal Synchronization
• Data Storage / Memory Latches
• Sequential Logic Circuits
• Digital Control Systems
