Hello,

I would like to know what is the fanout capability of LVC and AUC series gates.

How many inputs can be driven by the a single LVC or AUC output?

Thank you,

Hi Daniele,

Do you mean CMOS inputs?

The answer depends mostly on the total capacitance on the output (so the cumulative capacitance of all of the inputs being driven). You can drive up to 70pF on the output of any of our devices, though we typically recommend no more than 50pF. This would be about 7-10 inputs.

Best,

Malcolm

Thank you for your reply.

With inputs I mean LVC/AUC inputs. So inputs from the same family.

Hi Daniele,

Then a conservative estimate would be about 7 devices/inputs.

Best,

Malcolm
