TS3A44159: Replacing ADG734

Part Number:TS3A44159

Hi Expert, 

This is Roy Hsu, an FAE from Taiwan.

 My customer is currently using ADG734 (http://www.analog.com/media/en/technical-documentation/data-sheets/ADG733_734.pdf) and we are trying to replace it with our device.

 I did a quick search but didn’t find any suitable option.

 Could you please provide suggestion? ( It’d be great if we got pin-to-pin solution)

 Thank you!

Best regards,

Roy Hsu
