64 x 9-bit organization (IDT72421)  
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  
applicableforawidevarietyofdatabufferingneedssuchasgraphics,localarea

8,192 x 9-bit organization (IDT72251)  
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  
TheseFIFOshave9-bitinputandoutputports.Theinputportiscontrolled  
bya free-runningclock(WCLK), andtwowrite enable pins (WEN1, WEN2).  
DataiswrittenintotheSynchronousFIFOoneveryrisingclockedgewhenthe  
writeenablepinsareasserted.Theoutputportiscontrolledbyanotherclock  
pin (RCLK) and two read enable pins (REN1, REN2). The Read Clock can

(OE)is providedonthe readportforthree-state controlofthe output.  
The Synchronous FIFOs have twofixedflags, Empty(EF)andFull(FF).  
Two programmable flags, Almost-Empty (PAE) and Almost-Full (PAF), are  
provided for improved system control. The programmable flags default to  
Empty+7andFull-7forPAEandPAF,respectively.Theprogrammableflag

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)  
For through-hole product please see the IDT72420/72200/72210/ the load pin (LD).  
72220/72230/72240 data sheet  
These FIFOs are fabricated using IDTs high-speed submicron CMOS  
technology.  
Industrial temperature range (–40°C to +85°C) is available
