The IDT72235LB is a high-speed, low-power synchronous FIFO memory with a capacity of 2,048 x 18 bits. It features a 10 ns read/write cycle time and supports dual-port architecture with zero fall-through time. The FIFO includes fixed flags for Empty and Full status, 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 can operate with asynchronous or coincident read and write clocks, providing flexibility in system design. It is available in a 64-lead thin quad flatpack (TQFP) and plastic leaded chip carrier (PLCC) packages, and supports an industrial temperature range of -40¬8C to +85¬8C. The product is suitable for applications requiring efficient data management and buffering capabilities.
