Logic Flip-Flops are logical circuits that are built with bistable multivibrator, it consists of cross-coupled inverters or NAND gates or NOR gates. The output of flip-flop consists of two stable states, the states are known as S and R. For example, a flip-flop with logic 0 at the S and R inputs will result in logic 1 at the Q output and logic 0 at the Q output.The 74LVC273D is an 8-bit Register-Latch designed for low voltage (3.3V) application. It can operate at frequencies as high as 100MHz, and is suitable for low voltage logic designs. It has two clock inputs, CLK and CLK, and allows multiple types of latches and registers among its various outputs. The output of the register consists of flip-flop, this consists of two stable states, the states are known as S and R. This flip-flop can be also configured to have a D-type flip-flop or latch mode.The 74LVC273D has an enable input which can be used to enable or disable the inputs. The enable input is used in the form of logic 0 to enable or logic 1 to disable the inputs. The IC also contains address buffers, these buffers are used to drive address lines enabling the device to be used in multiplexed memory systems. The address buffering feature of the 74LVC273D is what makes it suitable for high speed memory systems.The 74LVC273D is commonly used in products such as microprocessors, digital systems, and communications systems. It is also suitable for low power designs as it draws very low power when in standby mode. The device is also used in applications such as memory controllers, timers, UARTs, DACs and other microcontroller peripherals.The applications in 74LVC273D are typically found in any low voltage logic circuit. It is useful for shift register type operations, bus lines, and so on. Its principal use is to hold the values of its inputs over time, or to shift bits through the device. Commonly, the combination of its latch and register functions are used to construct a working 8-bit register in a very small size. The working principle of 74LVC273D is based on the two-state flip-flop bistable multivibrator that is used to store data. The flip-flop stores a binary state of logic 0 or logic 1. Depending upon the voltage level at the S and R inputs, logic level 0 or logic level 1 is stored in the flip-flop. The enable (E) input allows us to enable and disable the flip-flop. The clock input is used to change the state of the flip-flop. When the clock pulses on the flip-flop the state of the S and R inputs is stored in the device. The 74LVC273D flip-flop is a very useful device for low voltage logic designs. Due to its low power consumption it is suitable for mobile and battery powered logic circuits. It allows multiple types of latches and registers on its various outputs, this makes it very useful for high speed memory systems. Additionally, it is cost effective and small in size, thus making it a suitable and efficient logic device for all kinds of low voltage logic applications.
