APPLICATION INFORMATION
1998 Jan 23
4-bit x 16-word FIFO register
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 (see Fig.7).
The PC74HC/HCT40105 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.
Fig.17 Expanded FIFO for increased word length; 16 words
