Product specification
4-Bit x 64-word FIFO register; 3-state
74HC/HCT7403
With FIFO full; SI held HIGH in anticipation of empty location

FIFO is initially full, shift-in is held HIGH
SO pulse; data in the output stage is unloaded, “bubble-up” process of empty location begins
DIR HIGH; when empty location reaches input stage, flag indicates FIFO is prepared for data input
DIR returns to LOW; data shift-in to empty location is complete, FIFO is full again
SI set LOW; necessary to complete shift-in process, DIR remains LOW, because FIFO is full.
Fig.7 Waveforms showing bubble-up delay, SO input to DIR output and DIR output pulse width.
