Logic - Flip Flops

Logic Flip Flops are a type of electronic circuit that consists of a small set of flip-flops. This type of circuit is used to store and distribute data from one node to another in digital systems. Flip Flops are designed to store a single bit of information such as a voltage or current value. Typically, logic Flip Flops are built with a single flip-flop on each clock cycle, and can be arranged in various configurations including SR, D, T and JK. Flip Flops are commonly used in a variety of applications, including digital data storage and transfer, memory-mapped device control, clock signal distributions and even analog signal multiplexing and demultiplexing.

SN74LVTH574DW is one type of logic Flip Flop. It is a combination of D-type flip flop and 3-state bus Buffer. The SN74LVTH574DW logic Flip Flop is designed for low-voltage applications. The device is designed to operate from 3.3V to 5.5V and it provides full-tolerance for low voltage of operation, minimizing the need for level shifters.

Application Field

The SN74LVTH574DW Flip Flop is suitable for a wide range of applications that require low power, fast signal propagation and accurate signal timing. It is commonly used in data transfer and signal conditioned applications. It can also be used in data multiplexing, digital signal processing, signal conditioning, communication interface and other logic systems. The Flip Flop also features 3-state capability, making it an ideal choice for memory-mapped devices and multi-drop buses. Moreover, the device features an independent control output, allowing it to be used for multiplexed data transfer. It also features low Quiescent Current, making it ideal for low power applications.

Working Principle

The SN74LVTH574DW logic Flip Flop consists of two flip flops and a 3-state buffer. The two flip flops are cross-coupled, and the buffer is used to set or reset the flip flops. The flip flops are usually preset with the first input, and then reset with the second input. When the first input is asserted, the flip flop is set to a "1". When the second input is asserted, the flip flop is reset to a "0". The output of the flip flop is the logic state stored in the flip flop at that time. The 3-state buffer is used to control the output of the flip flop. When the buffer is enabled, the output of the flip flop is enabled, and when the buffer is disabled, the output of the flip flop is disabled.

The SN74LVTH574DW is a combination of two components, a data latch and a 3-state buffer. The data latch stores the data and the 3-state buffer controls the output of the Flip Flop. The SN74LVTH574DW is designed for low power applications and is capable of running on any voltage from 3.3V to 5.5V. It is an ideal device for transferring data over multiplexed buses and for conditioning signals in digital signal processing systems.
