Product specification
4-Bit x 64-word FIFO register; 3-state
74HC/HCT7403
Note to Fig.18
The “7403” 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.18 Expanded FIFO for increased word length; 64 words x 10 bits.
