DESCRIPTION
The IDT72V3631/72V3641/72V3651 are pin and functionally compatible
versons of the IDT723631/723641/723651, designed to run off a 3.3V supply
for exceptionally low-power consumption. These devices are monolithic high-
speed,low-power,CMOSclockedFIFOmemory. Itsupportsclockfrequencies
up to 67 MHz and has read access times as fast as 10ns. The 512/1,024/2,048

has retransmit capability, which allows previously read data to be accessed
again. The FIFO operates in First Word Fall Through mode and has flags to
indicate empty and full conditions and conditions and two programmable flags
(Almost-Full and Almost-Empty) to indicate when a selected number of words
