APPLICATION INFORMATION
December 1990
9-bit x 64-word FIFO register; 3-state
The PC74HC/HCT7030 is easily expanded to increase word length. Composite
DIR and DOR flags are formed with the addition of an AND gate. The basic
operation and timing are identical to a single FIFO, with the exception of an added
gate delay on the flags.
This circuit is only required if the SI input is constantly held HIGH, when the FIFO
is empty and the automatic shift-in cycles are started or if SO output is constantly
held HIGH, when the FIFO is full and the automatic shift-out cycles are started
(see Figs 7 and 10).
Fig.17 Expanded FIFO for increased word length; 64 words
Fig.18 Expanded FIFO for increased word length.
