The IC component 74LVT574MSA is a octal D-type flip-flop with 3-State outputs, manufactured by the semiconductor company Texas Instruments. It belongs to the LVT family, which is renowned for its low voltage and low power consumption characteristics. This particular component is equipped with several key features that make it suitable for various digital logic applications.
The 74LVT574MSA IC features eight independent D-type flip-flops, each having a common clock (CP) input for synchronous operation. The input data (D) is stored on the rising edge of the clock signal when the enable signal (OE) is high. The flip-flops also have an active-low asynchronous reset (MR) input, which can be used to reset all the flip-flops simultaneously.
One significant feature of this IC is the 3-State outputs. It means that the Data Outputs (Q) of these flip-flops can be put into a high-impedance state (disconnected from the bus), controlled by the Output Enable (OE) signal. This feature allows multiple devices to share a common bus without interfering with each other, enabling bus sharing and reducing the number of I/O pins required.
Another noteworthy aspect of this component is its wide voltage operating range. It can operate with voltages ranging from 2.7V to 3.6V, making it compatible with various modern digital systems, including those powered by low voltage sources
