OPERATING CONFIGURATIONS
SINGLE DEVICE CONFIGURATION - A single IDT72420/72200/72210/
72220/72230/72240 may be used when the application requirements are
for 64/256/512/1,024/2,048/4,096 words or less. See Figure 10.
WIDTH EXPANSION CONFIGURATION - Word width may be increased
simply by connecting the corresponding input control signals of multiple
devices. A composite flag should be created for each of the endpoint status
flags (EF and FF) The partial status flags (AE and AF) can be detected from

IDT72420/72200/72210/72220/72230/72240s. Any word width can be
attained by adding additional IDT72420/72200/72210/72220/72230/72240s.
