IC 7476 Dual J-K Flip-Flop, Preset & Clear

The 74LS76 IC is essentially synonymous with JK flip-flops, primarily employed for bit storage but also demonstrating utility in various other applications. Several key attributes contribute to the widespread popularity of JK flip-flops, including:

• The clock input feature.

• The presence of preset input pins.

Notably, JK flip-flops exhibit state transitions upon the application of a clock pulse signal, which can manifest as either a positive or negative edge. Furthermore, the 74LS76 possesses the capability to filter out invalid output conditions.

The following is the pin description of 74LS76:

74ls76 Pin Details:

• 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 LO
