DESCRIPTION:
The IDT72413 is a 64 x 5, high-speed First-In/First-Out (FIFO) that loads
andemptiesdataonafirst-in-first-outbasis. Itisexpandableinbitwidth.Allspeed
versions are cascad-able in depth.
TheFIFOhasaHalf-FullFlag,whichsignalswhenithas32ormorewords
in memory. The Almost-Full/Empty Flag is active when there are 56 or more
words in memory or when there are 8 or less words in memory.
