Part Number: ISO7842 Tool/software: Hi Expert,
My customer is using ISO7842DWE package, for pin7, it is not connected in the datasheet, but customer want to connect 3.3V power with 300-500mA continues current.
I am not sure if this pin is high impendence…
Part Number: ISO7842-EVM Other Parts Discussed in Thread: ISO7842 HI TI Team,
ISO7842-EVM Evaluation Module has an I/O interface connector looking like SMA but is not able to find male or female. So please confirm whether the I/O interface connector is…
Part Number: ISO7842 Hello team,
I have a question from the customer.
Is there a limit to the number of times ISO7842DWW can be reflowed? The customer is asking if it is possible to reflow twice. I have confirmed that the data sheet states that the peak…
Part Number: ISOW7841 Other Parts Discussed in Thread: ISO7842 , Greetings.
Based on TDS, it has been stated that the parts are conform to UL compliance.
However, there are no UL marking on the physical parts ISO7842 and ISOW7841.
I have attached supporting…
Part Number: ISO7842 Dear TI-team,
we are currently developing a system that needs to isolate 1500V DC from PELV circuits. 1500V DC are required for the intended use, while from the PELV circuits power and signals are routed.
Now, the ISO7842 ensures…
Part Number: ISO7842 Hi Team,
Design question: The specific problem I'm looking at is isolating a high voltage (~4kV), high-ish frequency (~1MHz) signal from some low voltage digital circuitry. The ISO series looks nice, particularly the ISO7842FDWW…
Hi Hui,
ISO7820FDWWR & ISO7840FDWWR can definitely pass 7400 V AC for 5 seconds. Also, ISO7842 definitely passes 7400 V AC for 5 seconds. You can refer to isolation capacitor life time projection in ISO7842 datasheet at:
