Other Parts Discussed in Thread: ISO7640FM Hello, we are developing a product that needs to touch 480VAC lines. The ISO7640FM was found with very high isolation ratings but noticed that the working voltage per datasheet Description is 400 volts RMS. Note;…
Hi Justin,
You can use ISO7640FM for your prototype. The DC charge spread issue doesn't impact the integrity of the isolation barrier, so it's not going to create a hazard. The issue may temporarily show up as functionality problem if exposed to high…
Other Parts Discussed in Thread: ISO7640FM , ISO7140FCC Hello,
Are there any power up/down requirement between Vcca and Vccb for ISO7640FM, ISO7140FCC?
In the Function table in the datasheet, if Input VCC: PU and Output Vcc:PD, output state is undetermined…

Our customer want to use Digital Isolator for Virtex6 LVCMOS 25 I/O. Please see the below url page 39 as Virtex6 LVCMOS 25 DC level. http://www.xilinx.com/support/documentation/user_guides…
Other Parts Discussed in Thread: ISO7640FM I need to isolate an ethernet RJ45 LAN connection. Therefore i wanted to use optical couplers, cause i need a garantee, that i can't sent anything on the ethernet-port.
So my Question is, if i can use the…
Hi Rodrigo,
Yes, ISO7640FM is pin-to-pin compatible with ISO7740DW. Since the two devices belong to different families, they have many differences in performance like isolation voltage, power consumption among others. I would recommend you to go through…
Hi Mikhail, Thank you for posting to E2E! To transmit a unidirectional 24MHz CLK (48Mbps), either our ISO67xx family of devices or ISO77xx family of devices are recommended -- the ISO77xx family supports higher datarates and has more channel configurations…
Other Parts Discussed in Thread: ISO7640FM , ISO7740 hi
I would like to implement isolated I2S communication with master clock from oscillator and I want to ask you for some advices about it.
I found ISO7640 which is 150Mbps, but I am not sure whether 98…
Hello Kobayashi-san,
The UCC28950 should soft start the output rail. There are two ways this can be achieved:
Short SS/EN pin to GND until all power sequencing is complete (Vin → Vbias → Vbias2). Release SS/EN short to GND to start the controller.…
I don't know if that interference is of the kind that can be avoided with an isolator.
But if you want to use isolators , you have to use multiple chips. And the fastest would be ISO7640FM with 7 ns.
