LM321LV: LM321LV

Part Number: LM321LV

Hi


Can you please help to address below queries from my customer?

We are using an LM321LVIDBVR and our parts are marked as 1SPF and they are in the SOT-23-5 package.  According to the TI datasheet the pinout for the DBV package is shown on the left side of the attached scan.  The datasheet is SBOS944A revised Jan 2019.  Our board PCB footprint was designed for that footprint.  However, the parts we have received are actually pinned out like the DCK SC-70 package shown on the right side of the datasheet, even though they are in the SOT-23-5 package.  We discovered this because our simple differential amp circuit did not work.  Once I reworked the pinout for the SC-70 package into our board the diff amp worked fine.

 

So, what has happened here?  Am I missing something?  We have the SOT-23-5 package but it is bonded out like the SC-70.  Can you please help us understand if the datasheet is wrong or the bonding is in error?
