Hi all,

I would like TINA-TI model for SN74HCS72-Q1 to simulate /PRE pin behavior. Can you make this?

Hi RYO,

I can make this model for you. Please allow me a week to make this.

Thanks!

Hi,

I have created the following model. I have done some tests with it but if you see some use cases where it doesn't work please let me know.

SN74HCS72.CIR

SN74HCS72.TSC

Thanks!

Hi Karan,

FYI: I'm observing the following odd behavior with this SPICE model from https://www.ti.com/lit/zip/sclm299...

If I use separate supplies to tie the CLR and PRE pins high, the model works fine.

However, if I connect the PRE and CLK pins to the same supply or tied them to VCC the simulation does not work. i.e. I don't see any activity on Q or Q_N.

Hi Chris,

Yes, our D-Flip Flop PSpice models are really finicky. I'm afraid there's not really much I can do to fix this issue.

Thanks!
