Alternate IC for ADG1434 with power off protection

Hi all,

 

We are using Quad SPDT switch ADG1434, in one of our designs.

In our design, the input lines may be driven even when the power is off.

 

Below disucssion suggests that ADG1434 is not suitable for such applications.

 

ADG1434 Backfeed to Vdd when powered off

 

Although using ADG4612 solves power off problem, ADG4612 is a SPST switch.

I searched for QUAD SPDT analog switch with power off protection but couldn't find any.

 

Is there a alternate part to ADG1434, with power off protection ?

 

Please suggest.

 

Thanks,
