DESCRIPTION:  
The IDT72V805/72V815/72V825/72V835/72V845 are dual 18-bit-wide  
synchronous (clocked) First-in, First-out (FIFO) memories designed to run  
off a 3.3V supply for exceptionally low power consumption. One dual

lent to two IDT72V205/72V215/72V225/72V235/72V245 FIFOs in a single  
package with all associated control, data, and flag lines assigned to  
independent pins. These devices are very high-speed, low-power First-In,
