Working Principle
The SN74LS175N is a Quadruple Positive-Edge-Triggered D-type Flip-Flop. It can be used to store and retrieve two bits of binary data. Its inputs consist of four positive-edge-triggered D-inputs and four clock inputs. Its outputs consist of four Q-outputs, which store the input data on the positive edge of the clock.
The circuit can be used to control the output of a digital logic device. Depending on the logic of the connected device, the flip-flop can be used to control the outputs at each positive edge of the clock signal. This device can also be used as an asynchronous counter or latch.
When power is applied to the circuit, initially, all four Q outputs are high. If the D inputs are held high at the same time, the Q outputs will remain high as long as the clock is held high. If the D inputs are held low at the same time, the Q outputs will remain low as long as the clock is held high. On the negative edge of the clock, the outputs return to the high state.
Conclusion
The SN74LS175N is a Quadruple Positive-Edge-Triggered D-type Flip-Flop which can be used to store and retrieve two bits of binary data. It has a wide range of applications and is used to control the output of a digital logic device. On the positive edge of the clock, the output is determined by the states of the D inputs and on the negative edge, the outputs return to the high state.
