R5106 delay chip

[max-man]

The R5106 is an 8-pin delay chip made by Reticon - does anyone know of
a modern day equivalent or a vendor that sells them please? I'm having
a heck of a job finding one that is reasonably priced - cheapest so
far seems to be about $35 which seems a bit expensive for such a
relatively rudimentary device.


Thanks

I have no idea how this particular delay is made, but if it involves
coils that are hand-wound, then the labor costs could be the reason for
the high prices.

I see - am I not then likely to find any below, say, $20 each?

"Bucket brigade" ?

I'm familiar with an earlier and larger device, the SAD1024 also made by
Reticon. It's an analog "bucket brigade" sampling device driven by a clock,
but it has no coils inside. After all this is an IC we're talking about!
I've not seen any for sale in a while, since pure digital samplling is
pretty much standard practice now. One way to find one might be to salvage
one from another old unit. Finding a broken unit for salvage is a project
in itself, of course.

One Net source suggests that the SAD512 (or SAD1024) is a drop-in
replacement which can be made to work with a little tweaking of the
bias levels. However, both are DIP-16, not 8-pin, so I'm not sure how
reliable the info is.

Anyway, here are the datasheets:

Thanks for that.

Can't see how someone could describe them as drop-in replacements if
they're 16-pin devices (as opposed to the R5106 being 8-pin).

So who sells these chips, and at what kind of price?


Cheers

if memory serves here, the leg outline is set up to match the 8 pin
versions., you can use the 16 pin version or 2 of the 8 pin versions
in the 16 pin socket.

I see, thanks.
