CMOS DUAL SyncFIFO™

DUAL 256 x 18, DUAL 512 x 18,

DUAL 1,024 x 18, DUAL 2,048 x 18

and DUAL 4,096 x 18

• Single or double register-buffered Empty and Full Flags

FEATURES:

• Easily expandable in depth and width

• The IDT72805LB is equivalent to two IDT72205LB 256 x 18 FIFOs

• The IDT72815LB is equivalent to two IDT72215LB 512 x 18 FIFOs

• The IDT72825LBis equivalenttotwoIDT72225LB1,024 x 18FIFOs

• The IDT72835LBis equivalenttotwoIDT72235LB2,048 x 18FIFOs

• The IDT72845LBis equivalenttotwoIDT72245LB4,096 x 18FIFOs

• Offers optimal combination of large capacity (8K), high speed,

design flexibility, and small footprint

• Asynchronous or coincident Read and Write clocks

• Asynchronous or synchronous programmable Almost-Empty

and Almost-Full flags with default settings

• Half-Full flag capability

• Output Enable puts output data bus in high-impedance state

• High-performance submicron CMOS technology

• Available in the 128-pin Thin Quad Flatpack (TQFP). Also

available for the IDT72805LB/72815LB/72825LB, in the 121-lead,

16 x 16 mm plastic Ball Grid Array (PBGA)

• Ideal for the following applications:

Network switching

Two level prioritization of parallel data

Bidirectional data transfer

Bus-matching between 18-bit and 36-bit data paths

Width expansion to 36-bit per package

Depth expansion to 8,192 words per package

• Industrial temperature range (–40°C to +85°C) is available
