Part Number: ISO7140CC Tool/software: Hi,
I use the ISO7140CC in my design (let's define it as a closed box) and found out that from outside the 2 ground of the chip (GNDI and GNDO) are shorted.
My question is: Is there a potential damage to the ISO7140CC…

I'm looking for something that will do a level shift from a 0V/3V3 digital control signal to +/-2V5 (signals to control a split-supply amp, where…
Part Number: ISO7140CC Other Parts Discussed in Thread: ISO1410 Hi Team, Can we confirm if this device would work with LVDS signal (RS 422).
Thank you very much for your advice.

Part Number: ISO7140CC Hi team,
The customer wants to know the carrier frequency of the internal oscillator to see what frequency range can be generated. Could you give me comments on this question? They're asking because they want to consider what…
Part Number: ISO7140CC Hello,
I'm looking for FIT Data for ISO7140CCDBQR but wasn't able to find it in the typical location (Quality and Packaging tab). Can this be provided?

The figure above shows the recommended operating conditions for the ISO7140 digital isolator, where VCC2 is 2.7V~5.5V.
Because my circuit design is wrong, now VCC2 power supply up to 8V, can the chip be able to support 8V power…
Hi Steve,
The refresh tha the competition implements is on every channel and is periodic, whereas we have a separate watchdog/low-frequency channel that packetizes data for all channels in a given direction. There's no fixed tone for us, with some frequency…
Stef,
Sorry for the delay. Here are ISO7140CC waveforms for V CC1 power-up and power-down.

For this set, the rise and fall time of V CC1 is 50ms. For rise and fall times in the range you mentioned, the acquisition…
For isolation device, , ISO7140CC can be used for SPI isolation.
For the SPI signal, it is recommend to use a SN74ALVC244 or similar device just in front of each board. But 2MHz SPI speed is too fast, it's better to slow down to 200kHz level as there…
