DESCRIPTION:  
FEATURES:  
The IDT7280/7281/7282/7283/7284/7285 are dual-FIFO memories that  
loadandemptydataonafirst-in/first-outbasis.Thesedevicesarefunctional  
andcompatibletotwoIDT7200/7201/7202/7203/7204/7205FIFOsinasingle  
packagewithallassociatedcontrol,data,andflaglinesassignedtoseparate  
pins. The devices use Full and Empty flags to prevent data overflow and  
underflowandexpansionlogictoallowforunlimitedexpansioncapabilityinboth  
word size and depth.  
The IDT7280 is equivalent to two IDT7200 256 x 9 FIFOs  
The IDT7281 is equivalent to two IDT7201 512 x 9 FIFOs  
The IDT7282 is equivalent to two IDT7202 1,024 x 9 FIFOs  
The IDT7283 is equivalent to two IDT7203 2,048 x 9 FIFOs  
The IDT7284 is equivalent to two IDT7204 4,096 x 9 FIFOs  
The IDT7285 is equivalent to two IDT7205 8,192 x 9 FIFOs
