TMUX4052: +/- 5V supply margin

Part Number: TMUX4052
Other Parts Discussed in Thread: CD74HC4052

Hello team,

My customer is considering TMUX4052 to operate in +/- 5V supply.

However, the recommended operating condition states that minimum VDD should be 5V.
My customer want 10% design margin, so when they use 5V, the minimum supply spec should be 4.5V.

Isn't there any supply margin for this device?
Usually, when the device is meant to be used for 5V, the minimum supply is 4.5V.

If this VDD spec can't be compromised, is there any 4:1 MUX with +/- 5V operation with VDD minimum 4.5V?

Best Regards,
Kei Kuwahara

    I doubt that 4.5 V would be much of a problem. But the datasheet does not guarantee it.

    Anyway, the CD74HC4052 would not allow more than 10.0 V. But the TMXU6209 does what you want.

    Hi Kei,

    So at low speeds you could operate the device at 4.5V, but as Clemens mentioned the datasheet does not guarantee this operation over the long term. 

    Are you needing the higher end of the supply capabilities of this device? The CD74HC4052 that Clemens also mentioned would be a great alternative if you're strictly using +/-5V operation. 

    Regards,
