This document is about IDT72801/72811/72821/72831/72841 product introduction manual, introduces the features and characteristics of the product, including capacity, speed, design flexibility and miniaturization. It also introduces application scenarios, including prioritization, bidirectional, and width expansion applications.
The IDT72841 is a dual synchronous FIFO device functionally equivalent to two 72241 FIFOs in a single package. It offers 4096 x 9 capacity with 20 ns read/write cycle time. The device includes separate control, data, and flag lines for each FIFO, with programmable almost-empty and almost-full flags. It is fabricated using IDT’s high-performance sub-micron CMOS technology and is available in a 64-pin TQFP package for commercial applications.
The device supports flexible configurations including bidirectional operation, width expansion, and depth expansion. It features separate clocks and enables for write and read operations, with output enable pins for three-state control. The datasheet provides pin descriptions, electrical characteristics, and absolute maximum ratings for commercial operation.
