I am constantly running into a need for a shift register in my designs to
convert serial to parallel data (or vice versa). Yet as far as I've found,
the most "modern" one available is the Fairchild 74AC299. It would be very
nice, indeed, almost mandatory, to find parts with more modern processes
(2.5/1.8/1.5V logic), and wider word sizes (32-bit?). Are there any parts
out there you can recommend?
Why do none seem to be made? It seems to me almost self-evident that
somehow there must not be the demand, but I'm baffled as to how that could
be so? Aren't people needing high-speed serial/parallel or parallel/serial
conversion any more? If not, why not? If it's still a function that they
need, what are they using? Please don't tell me that people are using an
SRAM combined with a counter. If so, what an inefficient design, with more
needed components, more complex interfacing, wasted SRAM bits, etc!
