Replacement for 74189 IC

[Nerdium]

This thread is time sensitive, Please respond quickly.

 

The replacement I am looking for is for the 74189 Tri-State 64 bit RAM, In CDIP/PDIP form. To the extent of my knowledge, I see that most companies do not manufacture this IC any longer. Is there a replacement for this chip? If you are looking for replacements make sure it is 3-state, In CDIP or preferably PDIP format, and 64 bits.

Is this not it?

Jameco says it is out of stock and discontinued when viewed in the cart.

Here's one on eBay:

If you instead try searching for 74LS189 ICs?

 

Cant copy an Amazon link for some reason, but weren't 74LSxxx versions basically successors?

Maybe see if 74F189 would work

 

Signetics 74F189A  https://www.questcomp.com/part/4/74f189a/432920187

 

74F189AN     Philips Semiconductors     Static RAM, 16x4, 16 Pin, Plastic, DIP https://www.questcomp.com/part/4/74f189an/432920189

 SN74LS189AN    Texas Instruments http://www.bristolelectronics.com/sn74ls189an-ti/
  74LS189AN    Texas Instruments https://parts.com-sit.com/findchips/?part=74LS189AN

 

and if you're smart enough maybe you can use 74F219  which is same as 74F189 but has non-inverting data outputs (vs inverting outputs on 74F189)

Not familiar with that IC..it's more sophisticated...I need a replacement for a 8pin dip..the Protection IC it's a weltrand 5 something...Is there anyway to jump/start the units safe without it? and a different fan had burnt up the small middle inductor/winding piece on the apevia...don't have that either....

 

the shitty cheap unit's like the corsair and apevia use it...maybe a cap did it all too.

 

I don't know something ground referenced was killing it too and making it act up...lift ground and it was running and shit....
