Part Number: SN74LVC1G123

Could you please provide a one shot model use application in pspice simulation.

I use the one shot / 74123 model in spice. And I could not see the effect.

Could you please provide an example?

Thanks!

Hi,

The model we provide for this device is an HSPICE model. You need some sort of HSPICE software to use it; it will not work in a PSPICE environment. Please see below as to why we haven't developed any PSPICE/behavioral models for our MMVs:

What kind of HSPICE software you would suggest?

Also inside pspice software, a one_shot model do exist. Do you know how to connect it?

What does the pin R mean?

I've never used this one_shot model. I can try to use it tomorrow.

I have also unfortunately never used HSPICE so I can't recommend anything particular. From my knowledge it's quite expensive and is usually only used in military applications.

Best,

Malcolm

Hello Malcolm

Do you have some idea of using this model?

Thanks!

Hi,

In general we do not recommend using models for MMVs. they will not be accurate. You are better off doing your best to breadboard.
