The IDT72805LB is a dual 18-bit synchronous FIFO memory with a capacity of 8K words, designed for high-speed data buffering applications. It features a 10ns read/write cycle time and a 6.5ns access time, making it suitable for network switching, bidirectional data transfer, and bus-matching between different data path widths. The device supports both asynchronous and synchronous clocking, allowing for flexible integration into various systems. It includes programmable Almost-Empty and Almost-Full flags, as well as fixed Empty and Full flags for status indication. The IDT72805LB is available in a 128-pin Thin Quad Flatpack (TQFP) package and operates within an industrial temperature range of -40¬8C to +85¬8C. Note that the lead finish (SnPb) is in the end-of-life process, with the last time buy expiring on June 15, 2018.
