TMUX4052: TMUX4052 supply voltage range

Part Number: TMUX4052
Other Parts Discussed in Thread: SN74LV4052A

Hi,

Customer raised a question about TMUX4052. We know that you have modified supply range from 3V~12V to 5V~24V. Could you help to check what is the supply voltage with the data code of below chip？ Additionally, I would like to know why there was a modification in supply range?

Best regards,

Randy

    The chip has never changed. The "SCDS445" document was labelled as "Advanced Information".

    The minimum supply voltage was increased from 3 V to 5 V. The maximum supply voltage was not changed at all; ±12 V = 24 V. (If you want to use a switch for voltages like  5 V or below, use a low-voltage device like the SN74LV4052A.)

    Section 1 of the datasheet shows just some example configurations of the supply voltages. The exact limits are specified in section 7.4.

    Hi Randy,

    Clemens is correct here. The max voltage of the device didn't change - it's still 24V. The original datasheet was advanced information. This has now been changed to production data. Performance isn't optimized for 3V, so if you're needing to use the device with a 3V supply, I recommend going with the SN74LV4052 instead.

    Regards,

    Alex
