PCA9534: Device marking

Part Number: PCA9534

Hi.

Please tell me what the "SM" index means. (Photo attached)

Thank you!

  • Hi Oleg,

    These markings indicate the date (Y/M) and assembly location of the unit. The markings bellow that are the lot code. They are used to track units in production.

    Let me know if you have any more questions.

    Regards,

    Eric
