Re: [IBIS-Users] Mixed-Signal Analog IO ?

Hello All,

and Thank You for your valuable input. I will sift through your tips for 
some time and then decide how to handle this.

Thank You also for the below, I was unaware of this, being fairly new to 
IBIS modeling. Fortunately the clamp currents are ususally negligible in 
the normal operating area, maybe I do not have to redo all the models 
already made.
