Part Number: SN65ALS176
Other Parts Discussed in Thread: THVD1550

Hi Team,

 

 

Would like your support for component survey below. It is  important to Rockwell for component resiliency and risk assessment.

 

Supplier

Supplier Part Number

Component lead time

Supplier Est for Part Life Cycle Phase

(Introduction/Growth/Mature/Decline/Phase out/Obsolescence)

Supplier Estimate for Years to End of Life (In Years)

Customer Base Breadth

e.g. Wide (>50 customers)

Recommended Design Use for Supplier Part Number

Yes/No

Comments

Alternate recommendation or other comments

TI

SN65ALS176DR

 

 

 

 

 

 

 

Request your support to fill up the survey.

 

Note:

  1   .Please provide the Supplier Estimate for Years to End of Life in Years. Reply such as “No EOL plan” will not be helpful.

This is due to the fact that there is an internal process for accessing the component risk, thus we need a definite year of EOL to enable the calculation of risk index.

 

  1. RA product life in generally last for more than 10 years, it would be expected the component can last the same or longer. 

 

Thanks & Regards,

Saranya M

    Saranya,

    This part was released in 1987 and was just redesigned in January of 2023 - its over 35 years old and we just redesigned it in a new fabrication plant so that we can continue to support this device well into the future. RS-485 has not changed much in the 40 or so years its been around and this device sold well enough for it to warrant a redesign. We don't have an estimated EOL date because its not being EOL'd anytime soon. 

    All the other questions are about purchasing, which you will need to find that information at the point of purchase as those contact points will give you the other such information - such as the TI.com store, your field sales rep if you have one, or the 3rd party distributor that you work with.


    Best,

    The SN65ALS176 is an old bipolar device; the THVD1550 is a modern CMOS device with better characteristics (wider voltage range, better protection, much lower power consumption) at a slightly lower price. Therefore, there are customers switching from the ALS to the THVD, but none are switching back. While the ALS will not be EOL'd anytime soon, the THVD will have even higher demand. So if you care about component life time, you should choose the THVD instead.

    (The redesigned SN65ALS176 also is a CMOS device, but there is still no reason to choose it over the THVD unless you do not want to change the part number.)
