Logic - Flip Flops is an area of electronics which deals with the process of storing data and signals in a binary format. It is implemented with either digital ICs or analog ICs. Flip Flop is an important component of digital circuitry, and it has a wide range of applications in various fields such as timers, counters, memory, frequency dividers and more. One of the popular Flip Flops is the SN74LV273APWE4. Let\'s have a look at its application field and working principle.

Application of SN74LV273APWE4

SN74LV273APWE4 is a high-speed Dual D-type flip-flop integrated circuit (IC) which is capable of operating up to 100MHz (4 ns). This IC contains two D-type flip-flop with complementary outputs. The SN74LV273APWE4 can be used in many data storing and signal conditioning applications. It is often used in counter chips, pulse symbol generators, oscillators, frequency dividers and alarm systems. It is also used in static random access memory (SRAM) and dynamic RAM (DRAM) chips.

Working Principle

As mentioned above, the SN74LV273APWE4 is a dual D-type flip-flop IC. It works on the following two logic gates: NAND Gate and NOR Gate. The NAND gate consists of two input switches A and B. The NOR gate consists of three input switches A, B and C. Both of these gates have one output switch which is denoted with Q. When a signal is applied to both of the input switches of NAND gate, the output switch Q is turned on and when the signal is removed from both of the switches, the output switch Q is turned off. Similarly, for the NOR Gate, when a signal is applied to all three input switches of the gate, the output switch Q is turned off and when the signal is removed from any one of the switches, the output switch Q is turned on.

The SN74LV273APWE4 IC consists of two flip-flop circuits, one for each NAND Gate and the other for the NOR Gate. The flip-flop circuits are connected in such a way that when the output is triggered, it will remain in that state until a new signal is applied. This is called the “triggering” effect and it is used for storing data in memory chips. The flip-flop circuit works in the following way. When the preset (P) and clear (R) inputs are both low, the output (Q) is high. Then, when the R input goes high, the Q output turns off. Similarly, when the P input is high, the Q output will be turned off.

Conclusion

The SN74LV273APWE4 is a high-speed Dual D-type flip-flop IC which has numerous applications in data storage, signal conditioning and memory chips. It is a popular choice for many circuits as it can operate up to 100MHz (4 ns). The working principle of this IC is based on the two logic gates, NAND and NOR Gate. The flip-flop circuits are used to store data and signals in binary format and the data remain stored until a new signal is applied. Flip Flops are very useful and versatile components in digital circuitry and SN74LV273APWE4 is a great example of its application.
