The short answer is 'no'. I'm not sure what you mean by "pointing the other way". Do you mean every other pin offset to the 'rear' rather than to the 'front'? If so I've never seen that and it isn't in any datasheet I've had going back many years. The datasheet and TI.com will give you info on every option.
I think he means the one intended for horizontal mounting rather than vertical.
I do recall something like that, but it could have been one of the other LM38xx ICs or maybe the LM4780. I also seem to recall a pair of pliers intended for bending the pins. I could be hallucinating. Either way, I haven't seen those for years.

Maybe he got confused, 7294 does come in H and V versions for horizontal and vertical mounting, and it does have pins in two staggered rows (alternate pins are bent away).
At least the V version for vertical mounting does, same as LM1875 and similar.

Hi. Do anyone know where to find the LM3886 in stock? I live in Sweden and everywhere i look it is out of stock. There is a few on ebay and aliexpress but i fear that they will not be original and of lesser quality. I am in need of at least 2 but preferably 4.
Regards.

Try crating an account at TI, they show up off and on in small quantities at their on line selling site.
They seem to show up as available only to European and North American account holders...which is the reason I told you to try.
You cannot set up notifications, just keep an eye out for that, checking up regularly.
Some member may have extra, that is possible.
Unless needed for repair, simply opt for a similar substitute circuit, transistor / chip amp / Class D as per your choice.
Less mental stress.

Yeah, i have a account on TI but its out of stock there too but i do a check every few days.
Its not for repair but i wanted to make my first Chipamp.
Are there any recommendation on similar circuits that perform similar ti LM3886 if they are impossible to get?

Getting a few from ti.com is like winning the lottery, I believe only one member of this forum bought some directly from them in the last few months.
How much power do you need?
Class AB or D?
Stereo, or others like 2.1 / 4.1 / 5.1 / 7.1...the ready to connect populated boards are quite cheap here, you can get bare PCB as well.
Power supply, SMPS or linear?
What do you want to use an existing supply, or new?
Just browse this site after making that decision, tiny PAM series Class D to large transistor projects are described in detail, along with whatever issues cropped up.
For a small to medium room, the LM1875 is quite enough, two units in the same housing for stereo.
Speakers, you need good units, and their power handling capacity will also bear on your choice of amp.
I tend to use speakers with a higher capacity than my amps, less chance of clipping and other damage.

I really dont need that much wattage. the LM3886 is in the right ballpark and i only need stereo atm. I have 24-0-24v 300va transformer i was planing to use. but i will have to search for some other circuits with more easy to source parts i guess. 🙂

For the price of a pair LMs $12 you can get from Ali TDA7498e complete amplifier for 2x65W 8ohm near double 4 ohm. Convert it into ABD mod, you get by far superior amplifier.
See https://www.diyaudio.com/community/threads/convert-your-class-d-into-abd-modulation.396664/
For 24-0-24v 300va transformer , Tda7294 is available, take a look here: https://www.diyaudio.com/community/threads/xmas-amp-dibyas-tda7293-by-jhofland.365002/
I wonder which one will be generally available first, tl783 or lm3886, still looking into 2024?, just nuts. Maybe they are waiting for the new $billion fabs to be put on line first.
Oh that is strange. i have looked there a few days ago and thew where out of stock. Now a user on here contacted me and he had a pair so i will get them now at least. I will have to look at the Tda7294 amplifier too. Its fun to try new things 🙂
I would like to voice a warning for this ABD concept - it seems to be a noise/distortion generator....

I just checked TI.com and there are 234 (IIRC) LM3886TF (SnPb solder plated, not PB-free xxx/NOPB version) in stock. Order limit 10.
Today I checked the availability , nothing , and I clicked the “ notify me when available “ button ….. I didn’t get any email, what a joke!!!
They will not have anything to notify if there is no stock.
And that is about 25 orders worth, would have sold out in minutes.
It is like chasing a chimera, and it was leaded, so possibly old stock.
Somebody posted here, saying RS in UK has them listed as out of production.
Given that this is an old thread, and chip shortages are easing, decide whether you want to wait around, or use another device set.
