TMUX7209: Is the datasheet truth table correct?

Shady Gross

Part Number: TMUX7209
Other Parts Discussed in Thread: TMUX6209

The A0 and A1 columns appear to be swapped in the datasheet in table 9-2, TMUX72099 Truth Table. Please confirm that this is an error in the datasheet.

The columns are suspect because they do not follow the typical bit patterns, like those in table 9-1.

Link to the datasheet: https://www.ti.com/lit/gpn/tmux7209

The question references the current datasheet: SCDS418D – JULY 2020 – REVISED SEPTEMBER 2021

Table 9-2 is on page 34.

Incidentally, the table caption has an invalid part number (extra 9): TMUX72099 Truth Table.

Hi Shady,

Thank you for the note on the datasheet. I have checked this internally and confirmed you are correct, A0 and A1 are backwards on Table 9-2. I have contacted our internal team to fix this and propagate an updated version to the web. This should happen in a few days.

The table below shows the correct logic for this device.

If you have any other questions please let me know!

Thanks,

Stephen Scheramic
