Hi, I am considering using multiple ADG1414 Devices daisy chained together.
I will be supplying the chip via a single 12V supply.
I have a requirement to turn off switches immediately if a fault is detected. As there is no OE pin I will use the reset pin. However there seems to be a clause in the datasheet.
When using the RESET/V
L pin to complete a hardware reset, all other SPI pins (SYNC, SCLK, and DIN) should be driven low.
I can possibly get round this by AND gating the SPI signals with the reset line. My question is regarding the DIN signal of devices which are daisy chained. Will I also need to separately ensure that each DIN to individual devices are also LOW or will forcing the first device DIN LOW be sufficient ?
