The IDT72V81 is equivalent to two IDT72V01 - 512 x 9 FIFOs  
The IDT72V82 is equivalent to two IDT72V02 - 1,024 x 9 FIFOs  
The IDT72V83 is equivalent to two IDT72V03 - 2,048 x 9 FIFOs  
The IDT72V84 is equivalent to two IDT72V04 - 4,096 x 9 FIFOs  
The IDT72V85 is equivalent to two IDT72V05 - 8,192 x 9 FIFOs

Ultra high speed—15 ns access time  
Asynchronous and simultaneous read and write  
Offers optimal combination of data capacity, small foot print  
and functional flexibility  
The reads and writes are internally sequential through the use of ring
