Forum Post: ADS8028EVM-PDK: ADS8028EVM and DAC81416EVM Interconnect

Part Number: ADS8028EVM-PDK Hi all, We have two EVBs: ADS8028EVM and DAC81416EVM . And we have one SPI master. The question is, can these boards share the MISO signal wire directly? As shown in the Specs, the ADS8028 DOUT is a three-state output, and the DAC81416 SDO port seems be also three-state. But if we connect the DOUT of ADS8028 to the oscilloscope, it seams that the output of the DOUT keeps the last transferred bit after chip select is inactive. Is it safe to connect these two outputs to the MISO? Thanks in advance! Best regards, Jianxiong
