Hi team,

What is the minimum load capacity?
If you do not have a definite value, please tell us how to estimate it.

Best Regards,
Ryu.

There is no minimum, i.e., it's 0 pF.

What is the actual problem you're trying to solve?

I wanted to know for the max/min calculation of the CR time constant of the signal.

What matters for the Δt/Δv limit is the maximum capacitance; faster edges do not hurt.

Hello Ryu,

As Clemens stated, the input transition rate needs to be followed since there is no minimum load capacitance.

Josh
