TMUX6136: SEL1=Low selects S1B, right?

Katsumi Yamaoka

Part Number: TMUX6136
Other Parts Discussed in Thread: AM26LV32,

Hi,

In the datasheet[1], there seems no description about which port, S1A or S1B, gets selected by the High/Low level of SEL1 (or S2A/S2B by SEL2).  Although the Figure 20 looks SEL=High selects SB, the actual behavior we confirmed is SEL=High selects SA[2].  That's correct, isn't it?

I found a similar misprint in the AM26LV32 datasheet[3].  See the top-right of the Figure 4; A and B should be swapped.

Regards,

    Hi Katsumi,

    Regarding TMUX6136, please refer to the following table (1) from page 19 of the datasheet, confirming that SEL=1 connects SA to D. Thank you for pointing out the typo in Figure 20 (Transition-time measurement setup), we will update this accordingly.

    Regarding the misprint in AM26LV32 datasheet, please create a separate E2E post to confirm this with the team supporting this device.

    Thank you for bringing this to our attention!

    Best regards,
    Kate

    Hi Kate,
    Thank you for the quick reply.  Oops, this issue is absolutely due to my overlooking.  Or I should have made a question here.  Sorry for the noise anyway.

    Regards,
