4K x 18 / 8K x 9 TeraSync FIFO, 2.5V

Description

The 72T1855 is a 4K x 18 / 8K x 9 TeraSync 2.5V FIFO memory with clocked read and write controls and a flexible Bus-Matching x18/x9 data flow. Bus-Matching TeraSync FIFOs are particularly appropriate for network, video, telecommunications, data communications and other applications that need to buffer large amounts of data and match busses of unequal sizes. There are two possible timing modes of operation with these devices: IDT Standard mode and First Word Fall Through mode.
