Asynchronous Set and Clear: Can set or clear the flip-flops independently of the clock.
Positive-Edge Triggered: The flip-flops respond to the rising edge of the clock signal.
TTL Compatible: Compatible with standard TTL logic levels.
Registers: Useful in storage registers and data latches.
State Machines: Integral in designing sequential circuits and state machines.
Data Storage: Temporary storage of binary data.
Apply Clock: Use the CLK pin to provide clock pulses for triggering state changes.
Use Set and Clear: Apply low signals to the SET or CLR pins to asynchronously set or clear the flip-flops.
Monitor Outputs: Read the outputs QA, QA', QB, and QB' to determine the state of each flip-flop.
Pin 2(1 PRE'): Preset input for the first flip-flop, setting 1Q to HIGH. Active LOW.
Pin 3(1 CLR'): Clear input for the first flip-flop, resetting its output. Active LOW.
Pin 4(Input 1, J): First input for the first flip-flop, receiving data (HIGH or LOW).
Pin 5(Vcc): Power supply pin, providing operational power to the IC.
Pin 6(2 CLK): Clock input for the second JK flip-flop. A HIGH to LOW pulse affects the IC.
Pin 7(2 PRE'): Preset input for the second flip-flop, setting 2Q to HIGH. Active LOW.
Pin 8(2 CLR'): Clear input for the second flip-flop, resetting its output. Active LOW.
Pin 9(Input 2, J): First input for the second flip-flop, receiving data (HIGH or LOW).
Pin 10(2Q'): Second output for the second flip-flop, providing the inverted output of Pin 11.
Pin 11(OUTPUT 2Q): First output for the second flip-flop, offering its output bit.
Pin 12(Input 2K): Second input for the second flip-flop, receiving the second data bit (HIGH or LOW).
Pin 13(GND): Ground pin, creating a common ground with the power supply and other devices if required.
Pin 14(1Q'): Second output for the first flip-flop, supplying the inverted output of Pin 15.
Pin 15(OUTPUT 1Q): First output for the first flip-flop, providing its output bit.
Pin 16(Input 1K): Second input for the first flip-flop, receiving the second data bit (HIGH or LOW).

Description
The 74LS76 is a dual JK flip-flop IC with set and clear functions, part of the 74LS series of logic ICs. It provides two JK flip-flops in a single 14-pin package, each with an asynchronous set and clear inputs.Key Features:
Dual JK Flip-Flops: Contains two independent JK flip-flops.Asynchronous Set and Clear: Can set or clear the flip-flops independently of the clock.
Positive-Edge Triggered: The flip-flops respond to the rising edge of the clock signal.
TTL Compatible: Compatible with standard TTL logic levels.
Applications:
Counters: These can be used in binary counters and frequency dividers.Registers: Useful in storage registers and data latches.
State Machines: Integral in designing sequential circuits and state machines.
Data Storage: Temporary storage of binary data.
Typical Usage:
Connect Inputs: Provide logic levels to the J and K inputs to control flip-flop behavior.Apply Clock: Use the CLK pin to provide clock pulses for triggering state changes.
Use Set and Clear: Apply low signals to the SET or CLR pins to asynchronously set or clear the flip-flops.
Monitor Outputs: Read the outputs QA, QA', QB, and QB' to determine the state of each flip-flop.
Pin Configuration:
Pin 1(1 CLK): Clock input for the first JK flip-flop. A HIGH to LOW pulse influences this flip-flop.Pin 2(1 PRE'): Preset input for the first flip-flop, setting 1Q to HIGH. Active LOW.
Pin 3(1 CLR'): Clear input for the first flip-flop, resetting its output. Active LOW.
Pin 4(Input 1, J): First input for the first flip-flop, receiving data (HIGH or LOW).
Pin 5(Vcc): Power supply pin, providing operational power to the IC.
Pin 6(2 CLK): Clock input for the second JK flip-flop. A HIGH to LOW pulse affects the IC.
Pin 7(2 PRE'): Preset input for the second flip-flop, setting 2Q to HIGH. Active LOW.
Pin 8(2 CLR'): Clear input for the second flip-flop, resetting its output. Active LOW.
Pin 9(Input 2, J): First input for the second flip-flop, receiving data (HIGH or LOW).
Pin 10(2Q'): Second output for the second flip-flop, providing the inverted output of Pin 11.
Pin 11(OUTPUT 2Q): First output for the second flip-flop, offering its output bit.
Pin 12(Input 2K): Second input for the second flip-flop, receiving the second data bit (HIGH or LOW).
Pin 13(GND): Ground pin, creating a common ground with the power supply and other devices if required.
Pin 14(1Q'): Second output for the first flip-flop, supplying the inverted output of Pin 15.
Pin 15(OUTPUT 1Q): First output for the first flip-flop, providing its output bit.
Pin 16(Input 1K): Second input for the first flip-flop, receiving the second data bit (HIGH or LOW).
