DESCRIPTION:

72801/72811/72821/72831/72841 are dual synchronous (clocked) FIFOs. The device is functionally equivalent to two 72201/72211/72221/72231/72241 FIFOs in a single package with all associated control, data, and flag lines assigned to separate pins.

FEATURES:

? The 72801 is equivalent to two 72201 256 x 9 FIFOs

? The 72811 is equivalent to two 72211 512 x 9 FIFOs

? The 72821 is equivalent to two 72221 1024 x 9 FIFOs

? The 72831 is equivalent to two 72231 2048 x 9 FIFOs

? The 72841 is equivalent to two 72241 4096 x 9 FIFOs

? Offers optimal combination of large capacity, high speed,

design flexibility and small footprint

? Ideal for prioritization, bidirectional, and width expansion

applications

? 15 ns read/write cycle time FOR THE 72801/72811

? 20 ns read/write cycle time FOR THE 72821/72831/72841

? Separate control lines and data lines for each FIFO

? Separate empty, full, programmable almost-empty and

almost-full flags for each FIFO

? Enable puts output data lines in high-impedance state

? Space-saving 64-pin Thin Quad Flat Pack (TQFP)

? Industrial temperature range (-40°C to +85°C) is available,

tested to military electrical specifications
