Hi,

 

I am using ADG774 in one of our design. As per data sheet, it is a MUX. But i am using this as DEMUX i.e "D" as the source (SPI lines coming from FPGA) ans "S" as the load (SPI lines for PLL synthesizer for programming). Is it recommended to use this way? If so do you suggest any load requirement? The issue we are observing is the CMOS logic signal voltage drops at the load to less than 2.6 V.
