Part Number: CD4052B Other Parts Discussed in Thread: TMUX7309F , TMUX7349F Tool/software: We are using CD4052B in an automotive LIN circuit. While most of the time it works fine, we found that some were damaged. The voltage should not exceed 15V under…
Part Number: TMUX1209 Other Parts Discussed in Thread: TMUX6209 , TMUX7309F Tool/software: Hi, i developed a measurement circuiti in which the TMUX1209 is used to change the reference resistance of the circuit and so also to change the current flowing…
Part Number: TMUX7209 Other Parts Discussed in Thread: TMUX7309F , TMUX7412F I would like to use the TMUX7209 as a cell measuring multiplexer in a 4S lithium battery BMS. Because of the construction of the pack and the fact that we need to assemble with…
Part Number: TMUX1574 Other Parts Discussed in Thread: TMUX7309F , TMUX7462F Hello,
I need to implement protection on the TMUX1574 inputs against 60V, I am wondering if this CMOS chip has protection diodes to VCC and GND or not. If there are diodes…
The following table helps select th e right multiplexer and switch with Mid Voltage 25V =< VSIGNAL =< 99V in different configurations:

Hello Bryan,
Thank you for your quick response. The TMUX7309F might be a good candidate for this job. The VDD-VSS supplies are not an issue.
Ideally, the application would require a quad SPDT analog switch and all the CAN inputs protection, circuit…
What are Overvoltage & Fault events?
An overvoltage or fault event is when a signal with a voltage greater than the maximum rating of the analog switch or multiplexer is fed into the device. These events can occur for many reasons such as EMI from a…
Hi Ryoma,
the maximum supply voltage of OPA2991 is 40V and a special protection circuit against too high differential input voltages is used:

The TLV9152, on the other hand, has a maximum supply voltage of "only" 16V and can withstand…
Hi Corbett,
the footnote (4) in the absolute maximum ratings seems to indicate the presence of a protection scheme against too high differential inputs voltages, similar to what is used in mux-friendly OPAmps:

This can be responsible…
