LTSpice "High-Z" output

[gorka]

Hi everyone!

I've got a logic AND gate and I would like to set "High-Z" value instead of the 5V value. I'm currently editing the Spiceline2 value with "Vhigh="High-Z" Vlow=0 Ref=1.5 Trise=5n Tfall=5n Td=5n".

Thanks in advance,

gorka

Vhigh sets the logic-high voltage. Shouldn't you be setting the Rhigh and Rlow values?

Thanks a lot for your answer. For the next time, where am I supposed to look for the answer?

Hi
Those are static params that are read before a simulation run. Instead, use a switch contact in series with the gate output. Control the switch with "enable" pin.
