SN6501: SN6501DBVT Alternate requirement

Part Number: SN6501
Other Parts Discussed in Thread: SN6505A-Q1, , SN6505A, SN6505B, SN6505B-Q1, , SN6505D-Q1

Hey, We are using SN6501DBVT in our isolated power supply for the RS485 circuit. But currently, we are not getting this Ic from anywhere, can you please suggest any other Ic which has a pinout same as SN65 and we can replace that in our design without any modification.


  • Please also suggest any alternative to TPS76350DBVT

  • Hi Dheeraj,

    Thank you for posting to E2E!

    SN6501 has an automotive version (SN6501-Q1) available that is footprint compatible with its industrial part and functionally identical. SN6505 is also available in SN6505A, SN6505A-Q1, SN6505B, SN6505B-Q1, and SN6505D-Q1 versions, which are similar to SN6501, but not pin-to-pin identical. SN6505A devices also have lower switching frequencies, so they are not always compatible with isolation transformers used with SN6501 or SN6505B/D-Q1.

    Due to large demand of devices across products, we do not have many of these part numbers available on, and TI does not have any other push-pull isolation transformer devices. We recommend you subscribe to be notified once the device comes back in stock by clicking on the "Notify me when available" button under "Ordering & quality" tab on any of the devices' product pages as shown below:

    Please create a new E2E thread asking for an alternative to TPS76350DBVT so the LDO team may respond directly, and let us know if you have any further questions.

    Thank you,
    Manuel Chavez
