Part Number: TMUX1308-Q1

E2E, 

How does the common pin capacitance of TMUX1308-Q1 compare to SN74LV4051A-Q1? The capacitance is the biggest source of error with the SN74LV4051-Q1 for us today. Will using the TMUX1308-Q1 solve my issue? It’s hard to compare this since SN74LV4051A doesn’t provide a max value.  

The TMUX1308-Q1 provides a lower typical capacitance spec than the 4051 but a higher max value than the 4051. 

What is the max capacitance spec of the SN74LV4051A-Q1. 

Thank you,

Adam

  • Hey Adam,

    You're right in your assessment that we did not spec out the max common capacitance in the SN74LV4051A, so comparing is tricky. 

    My initial feeling is that since the TMUX1308-Q1 has a lower typical capacitance than the SN74LV4051A-Q1, that correlation would translate to the max value as well. That is to say that TMUX1308-Q1 probably has a lower common pin capacitance than the SN74LV4051A-Q1. However, I want to fully confirm this before committing to this answer. 

    I'm going to get some quantifiable results for you and get back as soon as possible.

    Thanks,
