Large ic's?

[kdaddy]

Anyone know what these are? Coming up empty on Google, ebay, etc. Came from ancient broadcast equipment.

Just the two? Smash them and find out!
Old can be very good, but how much can there really be in just two chips?

 

[kdaddy]

Lol, yeah maybe. I'm more curious as to the collector value.

Look like vintage DIP-Dual Inline Pin array IC-Intergrated Circuits.
Might try contacting this company for resell value.

As collector the pins are messed up, seems atleast.

It's likely a multi-channel or multi-phase delay line, used to delay digital pulses within a network (circuit) for timing, classification, and discrimination (elimination of pulses out of parameters). ESC made tons of them for military and computer use.

Many are just miniature shielded cable tightly wound up and potted, or a bank of small value capacitors, requiring the pulse to "store" before propagating further, introducing a tiny delay (pico or microseconds).

Aside from the gold on the pins, little else inside.

Thank you for the information!

 

[kdaddy]

Thank you all for the replies. I'll probably crack one open and save the other one just because.

It is a tapped analog delay line. They were used for coding and decoding of rf signals, especially radar pulses and below noise floor communication.

Welcome into the light frans. Nice first post.
