I agree with Peter.  The 74/54164 is a Serial In, Parallel Out shift
register.  Data is clocked in serially, and ends up on the parallel outputs.
This satisfies the original poster's request for Serial to Parallel
conversion.
A problem I can see with this IC, is there is no "update all outputs
uniformly" signal.  You will see the outputs change state as data gets
shifted across them before a bit reaches its final destination.  Not bad for
MMI's with a bank of LEDs, but not particularly suited for much else.

The '165, as noted, can do parallel to serial conversion.  I recently used
that very IC to read a bank of DIP switches, and save some precious PIC I/O
for other purposes.
