Zoey,
I think short answer is that you can use the DVDD to power two ISO7641 devices. However, there are limitations to that.
The ISO7641 current consumption depends on the data rate and how much capacitance the output is required to drive. If the capacitance…
Part Number: ISO7641FC Other Parts Discussed in Thread: ISO7741 Hi Expert,
The customer who make the power supply is asking the certification : IEC62368-1 A3 of ISO7641FC.
Pls let us know the status.

Hi,
Could you show me equation of the average lifetime? They seem to want to know how to calculate lifetime.
This question is related to below thread.

Hi Kuramochi-san,
Apologies for the delay in response, Abhi-san has been on travel for last several days hence couldn't respond. I have responded to your other related post that you have created recently. For completeness, I am copying my response below…
Other Parts Discussed in Thread: ISO7641FC Hello guys,
One of our customer is using ISO7641FC. The customer found that ISO7641FC doesn't work correctly at low temperature (-25C).
When they input 10kHz square waveform (duty 50%, 0-3.3V swing) to VIA…

Now here is the problem, I have…
Hi Frank,
For DC offsets, we're recommending our new digital isolator family, ISO734x. ISO7342C and ISO7341C/FC are planned to be released in 4Q14. Preview datasheet is attached.

ISO7641FC isn't recommended for DC offset…
Yes, you should not use ISO721 if your application requires 1200Vpk continuous operating voltage between input and output sides.
We don't have a single channel isolator with 1200Vpk working voltage but we have 2, 3, and 4 channel isolators that meet this…
Hello Raul,
our test engineers have the following suggestion:
Since the issue is occurring during high dV/dt it may be the ISO7641FM is responding to transient energy coupling onto inputs given the ISO7641FM does not have input filters.
Hence, could you…
