Hi Ning, Thanks for your assistance.
Regarding the 200nS delay. From IC signal to gate we have the 12V to 5V resistive divider, then the ISO7240CF isolator, then the UCC27714 gate driver. Measure delay through the resistive divider and ISO7240:
Around 65nS…

Dear Technical Support Team,
Unexpected momentarily glitch(about 2.5V , 8us) on the output during power up, at a time when Vcc2 is at about 2.5V.

Other Parts Discussed in Thread: ISO7240CF-Q1 , ISO7241C-Q1 , ISO7240C , ISO7240CF Hi Expert,
According to datasheet of ISO7240CF-Q1/ISO7240C-Q1, ESD protection is defined 4kV (I believe that this spec is Vpeak.).
However, there is no description about RMS…
Other Parts Discussed in Thread: ISO7240CF There is a description of “twake” in ISO7240CF datasheet p5.
Please tell me a min and max of “twake”.
Please answer it by December 4.
I would like to know what the ground current/quiescent current is for this device. The datasheet only specifies the ICCx (EN=HIGH) or Ioff (which is only the output current when EN=0V) and this does not give the ground/quiescent current of the device when…
You are correct, Calum, the '245 does not provide the classic definition of isolation. For digital isolation, you would have to use one of the ISO7xxx devices, depending on the configuration required. For example, for a 2TX/2RX configuration, the…

Matthew,
I have attempted to include an excel sheet from the Isolation Department's ISO University. It contains several links to collateral explaining isolation and it's applications. If the attachment failed, type "iso/" in…
