ISO7341C: ISO7341CQDWRQ1

Part Number: ISO7341C

Hello,

could I ask for help regarding the markings on your ICs?

For example, we are using the ISO7341CQ (ISO7341CQDWRQ1, bought from Mouser) in some boards/projects that must have traceability of most components.

The IC in questions has these markings:

first row: 99A66XT (with the TI logo in front)

second row: ISO7341CQ

third row: G4

Is it possible to gather any information that we could use for traceability, from the first and last row regarding lots, batches, dates, etc.?

Thanks

Marko

Hello,

Thank you for your question.

I have provided the details of each line on the IC below:

The first row indicates the Lot Trace code or LTC for short. for more details about the LTC, please refer to this document: /cfs-file/__key/communityserver-discussions-components-files/1013/4527.How-to-identify-STC-_2600_-LTC.PDF

The second row on the IC indicates the part number of the device.

third row: G4

The marking on the third row indicates the ROHS compliance of the device.
