Additional Details

The IDT72142L50P operates from a single 5V power supply and is available in a plastic DIP (Dual In-line Package) package. It supports both byte-wide and word-wide data transfers. The device includes flags to indicate when the FIFO is empty, full, or half-full, allowing for efficient data management. Its asynchronous operation makes it highly versatile for interfacing with various systems with differing clock speeds. The 50ns access time ensures fast data throughput, crucial for high-performance applications.
