SN74HCS74: Spice model does not seem to work in PSpice for TI

Klaas-Jan Winkel
Prodigy 60 points
Part Number: SN74HCS74

Tool/software:

Hi,

I have imported the SN74HCS74 cir file correctly in PSpice and simulation is now reporting 3x that NO1 pin is not connected. All pins have been connected. Could it be possible that this model is not compatible with pspice?

Regards,

Klaas-Jan

    To be more specific.

    the schema is:

    the error is:

    Hi Klaas,

    Let me send this to our modeling expert in the team to figure out the issue.

    I also want to add that this model is also not working in LT spice while the SN74LVC74 model is working. Looks like there is a something wrong with the spice model. Any news?
