How to simulate the outputs of comparator and the output of the NOR gate?

HI,
BUT on your circuit you have used a diode, so the inputs are clamped to 0.7v

The symbol is for a TVS, but it's modelled simply as a simple diode (D). You haven't specified any particulr TVS type/model.
ohhh

Note that in Eric's post #44 sim the A1 OR gate is actually providing a NOR output as v(out), because the inverting output is used.

but when specifying the model it i still dont see a change in the logic gate
Hi tie,
In your last posted image, you are still showing square wave input pulses of 5m/10mSec duration.
And yet you have set the Rise and Fall times of the Digital Gate to 10mSec.

You should be able to figure out why you have a triangular wave output from the Digital gate????
