The IDT72245LB is a high-speed, low-power synchronous FIFO memory with a capacity of 4,096 x 18 bits. It operates with a read/write cycle time of 10 ns and features dual-port architecture, allowing for asynchronous or coincident read and write operations. The FIFO includes status flags for Empty and Full conditions, as well as programmable Almost-Empty and Almost-Full flags, enhancing its usability in various data buffering applications such as optical disk controllers and Local Area Networks (LANs). The device is designed for easy expansion in both depth and width, supporting daisy-chain configurations. It is available in a 64-lead thin quad flatpack (TQFP) and plastic leaded chip carrier (PLCC) packages, and operates within an industrial temperature range of -40¬8C to +85¬8C. The product is in the end-of-life process, with the last time buy expiring on June 15, 2018.
