Part Number: ISO7721

Hello,

Our customer wants to know the Input capacitance of ISO7721.

Please let us know the max value when Vcc=5V and Vcc=3.3V.

Thanks and best regards,

Hiro,

The ISO7721 has an input capacitance of 2pF with Vcc = 5V when measured from input to ground. The capacitance value for when Vcc = 3.3V may take a day or so to deliver. Please be patient as a great deal of our team are on holiday.

Respectfully,

Hiro,

Thank you for your patience. The input capacitance for when Vcc = 3.3V is also 2pF.

Hello Lucas-san,

Thank you very much for your taking time to measure that.

I'll tell the customer that the input capacitance is 2pF at Vcc=5V and 3.3V

and it is measured value,not max.

Thanks and best regards,

Hiro

Hiro,

To clarify, these are maximum values and not measured. Input capacitance does not exceed 2pF.
