Team,

Customer is asking SN74LV4052APWR IBIS model. We provided TMUX1309 IBIS first, but TMUX1309 IBIS only has input model.

Can you help to provide output IBIS model too? or provide SN74LV4052APWR full IBIS?

Neither the TMUX1309 nor the SN74LV4052A has any buffered outputs. The control pins are inputs; the S/D/COM/Y pins are connected to transmission gates.

Unfortunately, the TMUX1309 IBIS file does not contain models for the switches (and its electrical characteristics would be different anyway). For how to model the switch, see [FAQ] How do I Approximate Propagation Delay and Channel to Channel Skew in an Analog Switch/Multiplexer?

Thanks Clemens. Customer is also asking if we can provide any SN74LV4052A data file that contains the following parameters?

Hi Yu-chen,

I'm not sure exactly what you mean by a datafile but if no IBIS file exists they'll need to create a passive model using the CON and RON from the datasheet and following this FAQ:

[FAQ] What if my Analog Switch/Multiplexer is Missing an IBIS Model?

Thanks,
Rami
