Same problem -- the serial outputs QA & QH cannot tristate.
It seems overkill to use a separate data selector chip as some
have suggested (though it would certainly work).  Maybe I'll end
up using the daisy-chain solution, but it would be neater to find an
SPI-friendly part.
Thanks to all,
Brian Aase
