Additional Details

The 74LVX161284 features a flow-through architecture, which minimizes propagation delay and enhances overall system performance. The LVX family designation indicates that it is designed for low-voltage operation, making it compatible with modern digital systems. The 3-state outputs allow for flexible bus configurations, enabling multiple devices to share the same bus. Proper power supply decoupling is critical for stable operation. Care should be taken to avoid exceeding the maximum voltage ratings on the input and output pins. Detailed datasheets and application notes are available from ON Semiconductor to guide designers in using the 74LVX161284 effectively.

This latch is commonly used in bus interface applications to transfer data between different buses or memory systems. It is also used in data multiplexing applications to select one of several data sources. Its high-speed performance makes it suitable for applications such as digital signal processing where data needs to be processed quickly. Proper PCB layout techniques are essential for minimizing noise and ensuring reliable operation.
