Hi Ali,

Unfortunately we don't currently have Tina-TI or LTSpice models for Flips Flops.

Regards,

Sebastian

Hi Sebastian, is there any similar model can you provide ?

Thank you

Hi Ali,

There are no Spice models I can provide, there is an HSpice model available on the SN74LVC2G74 product page. We also have an IBIS model to simulate I/O behavior.

Regards,

Sebastian

Hi again. Tina website says there is generic models for D flip flops in library

https://www.tina.com/components/

and this is the library

https://www.tina.com/English/tina/wp-content/uploads/2019/04/TINA-library.txt

BUT how do I find D flip flop ?

there is only numbers in library. can you provide names for models number in library ?

I just want Single Positive Edge Triggered D-Type Flip-Flop With Clear And Preset

Also, can you tell me what is exactly TG symbol on page 2 of the document ?

Thank you

Hello,

PSpice models are notoriously difficult to get working for latched circuits -- any latch has a feedback loop that includes memory, and can cause instability (ie singularities) in the node-voltage solution matrix.

I have a Tina-TI model for a D-Type Flip-Flop, but it is not 100% reliable. You can try it out in your circuit and see if it works though.

SN74LVC1G74_BETA.cir

And here is an example Tina-TI file using this model:
