DS26LV32AT: AM26LV32E a drop-in alternative?

Part Number: DS26LV32AT

Hi Experts,

Good day. Seeking your assistance please.

Customer needed DS26LV32ATMX/NOPB but due to unavailability, we found alternate as follows:

  • AM26LV32EIDR

Does this consider a drop-in replacement? Please also confirm whether it has any software impact?

Thank you.

Regards,
Archie A.

    Hi Archie,

    They are similar parts and both are available in same package/pinout and is probably the best option to replace. 

    The biggest difference I see between the parts is the timing specifications - the AM26LV32EIDR is rated 3.2x faster than the current device. You can still run the AM26LV32EIDR at the lower data-rate, but the transition times will be a bit quicker - so there will be more high frequency content generated with the AM26 than the current part - if the system is properly terminated and has been setup properly this shouldn't be that big of an issue, but it is a difference. 

    From a software perspective - really doubtful they have to change anything - both parts have the same control scheme so I don't think firmware would need to change since they function the same way and RS-485 doesn't have a firmware protocol tied to it so the devices don't have integrated firmware so no new code should be needed.

    Please let me know if you have any other questions!

    Best,
