TMUX1247: Voltage tolerance on the non-selected input

Charles McClelland

Part Number: TMUX1247

My question is on the voltage tolerance for the non-selected input. If the switch is say S1 is connected to D, then can the other input, S2 tolerate a higher voltage than the Vdd+0.5 which is called out in the datasheet? As long as S2 is not selected, can it handle 9V?

Thanks, Chip

Hi Chip,

applying more than Vdd+0.5V could damage the pin, no matter if it is selected or not. This is due to the internal CMOS structure of the MUX

Also the max voltage on VDD and SEL/EN is 6V.

Best regards,

Ambroise

Is there a part that could handle up to 9V?

Hi Charles,

In the same 1:2, 1 channel configuration, the TMUX6119 works well with dual supplies (±5 V to ±16.5 V), a single supply (10 V to 16.5 V), or asymmetric supplies.
