10 ns read/write cycle time  
Read and Write Clocks can be independent  
Dual-Ported zero fall-through time architecture  
Empty and Full Flags signal FIFO status  
Programmable Almost-Empty and Almost-Full flags can be set  
to any depth  
Programmable Almost-Empty and Almost-Full flags default to  
Empty+7, and Full-7, respectively  
Output enable puts output data bus in high-impedance state  
Advanced submicron CMOS technology  
Available in the 32-pin plastic leaded chip carrier (PLCC) and  
32-pin Thin Quad Flat Pack (TQFP)  
The IDT72421/72201/72211/72221/72231/72241/72251 SyncFIFO™  
are very high-speed, low-power First-In, First-Out (FIFO) memories with  
clockedreadandwrite controls. These devices have a 64, 256, 512, 1,024,  
2,048,4,096,and8,192x9-bitmemoryarray,respectively. TheseFIFOsare
