hi dear supporting team,
there is one concern from customer on both TS12A12511 and SN74CBTLV3257DBQR, for an example, with A port and B port input, and output to COM port, when they do the switch from A port to B port, during the process, because there is signal shown in both input, is it possible that there is a instant that both A&B data show in the COM? tks a lot!
Vera,
What are you trying to switch in your system that you are concerned that multiple pins can be connected to the COM pin during switching?
To ensure that multiple pins do not connect to the COM pin, signal switches have a feature call break-before-make. This means the COM pin will be disconnected from all pins during switching before it connects with the next pin. You can see this feature in the datasheets and search for the feature on the ti.com switch selection tool.
Thank you,
Adam
Vera,
There is a feature filter you can add on the ti.com switch search tool. What do you think about the TS3A5223 or the TS5A23160 that has powered off protection feature you requested.
Thank you,
Adam
