EHX ICs??

[Govmnt_Lacky]

I came across a small stash of Reticon ICs and I am not sure if they are used in EHX pedals or not. The part number is:

RF5611ANP-011

I know the RF5609s are used in the 16-second delay but, I am not sure if these are as well OR in another platform. I know I kept them around for a reason but, that reason escapes me for now 

Anyone??

Not to my knowledge, seems to just be the high pass counterpart to the 5609 and apart from an envelope filter, I can't see why a pedal would need one.
