Part Number: ISO7342FC Other Parts Discussed in Thread: ISO7740 , ISO7742
Hello,
I want to isolate SPI bus with 4 chip selects. (MOSI,MISO, CLK and 4 Chipselects). I use ISO7342 & ISO7340 for this purpose. MOSI, MISO and CLK lines are connected to…
Part Number: ISO7342FC Hi Team,
My customer is getting failures on the ISO7342FCDWR IC.
Pin 14, 13, 12, and 11 are directly connected to an MCU and problematic chips have pin 12 voltage lower that the expected.
It is being used for UART communication…
Other Parts Discussed in Thread: ISO7342FC Hi
My customer is considering to use the ISO7342FC for noise isolation. To start the design on the production level, they are now performing FMA on this device.
In this analysis, customer asked us their concern…
Hi Hyunjun,
Thanks for your response and the additional information.
The length of the traces are not long, you should be good to use the ISO7761 device in your system. This would also depend on your data rate, but if the data rate is not really high…
Nagai-san,
Yes, ISO7342FC has lower ICC requirements than ISO7242C. When EN = 1 for ISO7342FC, ICC1 = ICC2 = 2.5mA typical whereas when EN = 0 ICC comes down to 0.7mA typical.
