Default What is this chip ??

Does anyone recognise this chip number ?
It comes from an audio router unit and the manufacturer is no longer trading.
It's some sort of audio switch but I cant find anything on the web ??

Any ideas ?

It is a Siliconix DG212 CMOS analog switch. Siliconix was swallowed up nto the Vishay empire. The modern equivalent can be purchased from Farnell or other distributors.

This was def. a "spec savers" moment as it appeared I had been searching for DG 2121 !
Happily the link provided has enabled me to map out the usage of the device in the existing unt and I am now well on the way to rebuilding it in its new form.

Thanks all
