Hello,
VDD and A, B are powerless. Now customer apply 1.2V to Mux input (X0,Y0) or (X1,Y1) or (X2,Y2), and measure Mux Output 0.135V and Mux power as -0.5V. They expected it should remain 0V for power and output.
Regards, Holger

Hi, Holger,
The CD4052B does not support powered-off protection, and it would partially turn on if signals exist on the inputs with VDD=0V.
For more details on the powered-off protection and how to find a device with the feature, please refer to this E2E thread.

Hello David,
can you suggest a device that has similar footprint to CD4052 & supports powered-off protection.
Regards, Holger
Hi, Holger,
Which package are you looking for specifically? The CD4052B is offered in DIP, SOIC, TSSOP, and SOP packages.
You can find a list of devices that support powered-off protection by filtering the feature in the parametric search tool on TI.com. There are currently 8 devices in differential 4:1 configuration supporting the powered-off protection feature.
Thanks,
David
