The maximum input current of ISO7640FM

Other Parts Discussed in Thread: ISO7641FM

Hi all

I noted that the high level input current had to be less than 10uA while the digital input signals into ISO7640FW were at least 3mA. What should I do to fulfill this isolation function?

Thanks

    Hi Ted,

    Did you mean to say ISO7641FM is taking 3mA of input current? Or did you mean you want the device to take at least 3mA of input current?
    ISO7641FM only requires a maximum of 10µA as input current and it doesn't take anything more than 10µA even if the source is capable of.
