Delay line? Are they still in use?

romhunter:
The title say it all. I happened to get ahold of a full tube (digital delay line) and wonder if they're still in use? Or widely use?
helius:
The salad days of delay line chips may be in the past, when they were used for applications as diverse as PAL television decoding and oscilloscope trigger circuits. The most common use these days may be in cheap effects pedals, where they can be used to build reverb and chorus circuits.
NiHaoMike:
Got the datasheet? That should give ideas on what it can be used for.
Alex Eisenhut:
They still make em.

But there's also the other style that is a hex inverter with a bunch of LC delays between the elements built into a capsule over the DIP14. They are usually tapped along the way.

It's not a delay line. Basically just a buffer offering a little bit more delay than most of this TTL series. Delay line is for example TDA4665.
