My Client used ADT7301, As following is their schematic for ADT7301.
Due to the pull-up resistor, ADT7301 has ~1mA sink current from DOUT pin. Therefore, they have two questions to clarify.
I can't find more description of specifications for DOUT pin in datasheet or other document, so I can't clarify these issues to my customer, please help me, thanks.
May I know the customer application here? Where do the MISO, SCK, MOSI lines go to? Page 12 of the ADT7301 datasheet shows some examples of connecting the ADT7301 serial interface.
Hi,This is optical switch product and this product was mass Production . MISO, SCK, MOSI lines go to MCU. End customer of client listed the above two issues to My client. I and RD of client can't find maximum ratings value of sink current for DOUT pin on datasheet, could you help us clarify above issues? Thanks a lot.
