Other Parts Discussed in Thread: SN75ALS160, SN65C1167E, CY74FCT245T, SN74ABT245B
We recently received an EOL notice for the GPIB/IEEE-488 Transceivers (SN75160BDW and SN75161BDW). This announcement has caused some concerns within our team as we have a substantial amount of legacy equipment that still utilizes GPIB and which we continue to support. (ref. Texas Inst. PDN# 20230516001.3)
I understand the entire fabrication process for these parts is shutting down. We are particularly concerned about the lack of a form, fit, and function (FFF) drop-in replacement. This situation could require a significant redesign and retesting effort on our part.
Given the potential impact on our business, I would appreciate further information or guidance you could provide on this matter. Specifically, we're looking for clarification about TI's transition plan for these components.
Note:
There is confusion between the parts listed in TI's PCN and TI's website status for these parts.
The SN75160BDWR and SN75161BDWR versions are active with ten-year lifecycle, the datasheet states the package size is the main difference, with 2000 pieces per reel.
It’s curious that these versions aren't included in the PCN, are all fab sites for this part shutting down? Looking at TI's PCN, it states they're shutting down the entire fab site, all their devices, regardless of how they're packaged, are discontinued. Their statement about closing the 150-millimeter production at the current fab site is not providing alternate sites for these parts.
