LM1971: Multiple use of LM1971

Hi Experts,

Customer want to use 4 x LM1971 atten for their project.

For circuit design,

Is it possible to use control signals all  in common  to control 4x LM1971 ?

Or Is it possible to use tow signals (CLK/DATA) in common and separate 4 x load signal ?

Thanks,
JH.
