\$\begingroup\$ Can you put a bigger picture as well to show the surrounding components? Also give more information about the circuit e.g. what equipment that the circuit belongs to. \$\endgroup\$– Rohat KılıçCommented Aug 7 at 6:29

\$\begingroup\$ FWIW the device logo is from Siliconix (now Vishay) \$\endgroup\$– VelvetCommented Aug 7 at 6:50

It's a Vishay DG412DQ SPST analog switch.

I can't find a picture for the DG412, but here is one of the DG411DQ from lcsc.com that shows similar markings just with a 411 instead of 412.

\$\begingroup\$ +1 For a good answer. But just a side note: This appears to be a standardized part because there are multiple suppliers, like Analog Devices and Renesas, that also supply this chip. \$\endgroup\$– ColinCommented Aug 7 at 16:47
