Product specification
4-Bit x 64-word FIFO register; 3-state
74HC/HCT7403
Note to Fig.19
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.19 Expanded FIFO for increased word length.
