Allen-Bradley IC's

[Sody54]

Afternoon,

I'm finally taking the time to go through the rest of the bins of components my uncle gave to me.  (Had 5 of the plastic drawer units with 60 bins each)
I ran across quite a few items that I'm going to be putting up on the trading forum this weekend, but there are some IC's that I haven't been able to locate any info about on  the internet.  All I come up with on Google are links to part lists from component warehouses or obsolete semiconductor sellers, and the like.  No datasheets.

the chips are labeled:

316B102  8121
316B104  7944M
316B153  8128
316B221  8001M
316B392  7727

They're all 16pin DIPS and have the Allen-Bradley logo on them.   Anyone by chance know what the heck these are or what they'd be for?

thanks,
Brian

I would assume that they are resistor packs, a bunch of resistors in a handy DIP package for pull ups on busses and the like.

The last 4 digit #s for each one is the date code.  Not sure how to read the rest, but I would guess that the AB site might have some information.

To add the last 3 in the first set should be the resistor value.

IIRC  first numbers and letter indicate the pinout and wattage.  One type is 8 individual side to side, another is 1 common pin for a pull up or down pack.  I forget what number is what.  A google seach might find it.

I believe the 316 is the model number, and "B" designates bussed. So you have:

316B102  = 1K
316B104  = 100K
316B153  = 15K
316B221  = 220
316B392  = 3K9

Pretty useful for digital circuits, but I don't know how you could use them in a stompbox (unless you have 15 LEDs).
An Ohmmeter would tell, but the common lead is usually pin 1 or 16.

That's kinda cool actually.  Could be useful?

Maybe. On the bussed networks, one end of all resistors is tied together, the other ends come out seperate pins. So, if you need fifteen resistors on the same value, all tied to the same point in the circuit (ground, VRef, whatever), you could use one of these. They typically don't handle much power, though. The isolated networks have each resistor end connected to individual pins, so they can go different places.

Both suffer from the fact that all fifteen resistors reside at the same point on the layout - routing leads/traces in an analog circuit gets messy. These are perfect for what they were designed for - pulling digital bus traces to ground (or Vcc).

Thanks for the help!  I've got roughly 30 of the little boogers.  Should probably move this over to the sell/trade list, but would anyone like them?  You can have 'em.  I'll never have a use for them.   I'll ship them  anywhere in the U.S. if somebody would like to lay claim to them....

thanks again,

Brian
