Data Output
Data is shifted out on the HlGH-to-LOW transition of Shift
Out (SO). This causes the internal read pointer to be
advanced to the next word location. If data is present, valid
data will appear on the outputs and Output Ready (OR) will
go HIGH. If data is not present, Output Ready will stay
LOW indicating the FIFO is empty. The last valid word read
from the FIFO will remain at the FlFOs output when it is empty.
When the FIFO is not empty, Output Ready (OR) goes LOW
on the LOW-to-HIGH transition of Shift Out. Previous data
remains on the output until the HIGH-to-LOW transition of
Shift Out (SO).
Fall-Through Mode
The FIFO operates in a fall-through mode when data gets
shifted into an empty FIFO. After a fall-through delay the data
propagates to the output. When the data reaches the output,
the Output Ready (OR) goes HIGH. Fall-through mode also
occurs when the FIFO is completely full. When data is shifted
out of the full FIFO, a location is available for new data. After
a fall-through delay, the Input Ready goes HIGH. If Shift In is
HIGH, the new data can be written to the FIFO.
Since these FlFOs are based on an internal dual-port RAM
architecture with separate read and write pointers, the fall-
through time (tPT) is one cycle long. A word may be written
into the FIFO on a clock cycle and can be accessed on the next
clock cycle.

Figure 3. The Mechanism of Shifting Data Into the FIFO
NOTES:
1. Input Ready HIGH indicates space is available and a Shift In pulse may be applied.
2. Input Data is loaded into the first word.
3. Input Ready goes LOW indicating the first word is full.
4. The write pointer is incremented.
5. The FIFO is ready for the next word.
6. If the FIFO is full then the Input Ready remains LOW.
7. Shift In pulses applied while Input Ready is LOW will be ignored (see Figure 4).
