TMUX1133: Max power supply voltage

Part Number: TMUX1133

Hi team,

I promote TMUX1133 to my customer, but they want to use ±3.3V supply. I noticed that tmux1133 support ±2.5V.

Can you give some suggestions or recommend a low leakage current switch?

Thanks and best regards,

Colin

Hi Colin,

While we do not have that exact configuration that supports +/-3.3V, I would recommend using multiple TS12A12511 which is a 2:1, 1 channel switch that supports +/-2.7V to +/-6V and has good leakage performance at 500pA typical.

Thanks!

Bryan

Hi Bryan,

Thanks for your suggestion. Is there a multi-channel version？

Thanks,

Hi Colin,

There is no multi-channel version available today.

Please note that using 3x, TS12A12511 devices in the SOT-23 leaded package (TS12A12511DCNR, 3mm x 3mm) will be same w.r.t solution size (~27mm2| 32mm2 assuming a 20% space adder for 3x chips) vs the TSSOP (32mm2).

This will provide a 3ch, 2:1 solution too as required by the customer.

Thank you,

Regards,
Sandesh
