DESCRIPTION:
The IDT72V3622/72V3632/72V3642 are functionally compatible versions
of the IDT723622/723632/723642, designed to run off a 3.3V supply for
exceptionally low-power consumption. These devices are monolithic, high-
speed, low-power, CMOS Bidirectional SyncFIFO (clocked) memories which
support clock frequencies up to 100MHz and have read access times as fast
as 6.5ns. Two independent 256/512/1,024 x 36 dual-port SRAM FIFOs on
board each chip buffer data in opposite directions. Communication between
