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
