Product specification
4-Bit x 64-word FIFO register; 3-state
74HC/HCT7403
Note to
Fig.23
Sequence 1 (both FIFOS empty, starting SHIFT-IN process)
After a MR pulse has been applied FIFO
A
and FIFO
B
are empty. The DOR flags of FIFO
A
and FIFO
B
go LOW due to no
valid data being present at the outputs. The DIR flags are set HIGH due to the FIFOs being ready to accept data. SO
B
is held HIGH and two SI
A
pulses are applied (1). These pulses allow two data words to ripple through to the output stage
of FIFO
A
and to the input stage of FIFO
B
(2). When data arrives at the output of FIFO
B
, a DOR
B
pulse is generated (3).
When SO
B
goes LOW, the first bit is shifted out and a second bit ripples through to the output after which DOR
B
goes
HIGH (4).
