SN74ALS1034: logic

Part Number: SN74ALS1034
Other Parts Discussed in Thread: CD74HC4050, SN7400


I am using SN74ALS1034 for buff drive. It is becoming obsolete?

Can you recommend me any alternative with temperature range from -40C to 85C?



  • Hi Christie,

    I am not sure if the part is becoming obsolete. I will confirm that for you.
    Would the CD74HC4050 work for your application? You will need to provide me with voltages you are operating at. Do you need this to be pin to pin compatible?

  • Hi Christie,

    The following is TI's policy on obsolescence:

    The policy basically boils down to this: TI will continue to sell a device as long as we have a customer buying it, unless something happens that forces us to no longer be able to produce said device.

    In my opinion, if you regularly order a part on an annual or quarterly basis from TI, then it will continue to be available for you. As an example, we are still shipping SN7400 units that were first designed in 1969 because we have customers who continue to buy them -- most manufacturers stopped making these a long time ago!

    Also, if something did come up that we would have to stop making a device, TI would notify you well in advance of that happening (I believe the policy says 1 year, but I could be wrong). We can't predict what will happen in the future, but we do everything we can to support our customers.
