Hi Ankita,

Please use the IBIS model for the SN74HCS74. They should be functionally equivalent.

I checked the ibis model. It has 2.23, 3.3 and 5.5V supply. I need 5V ibis. Also, functionality wise are both the will be same when operating as driver?

Hi Ankita,

Functionality is the same. Our data is limited to what we have in the model, the 5.5V supply is all we have available. The weak PVT data for 5.5V also has data for 5V VCC.

Best,

Malcolm
