TCA9548A: TCA9548AMRGER vs TCA9548ARGER

Part Number: TCA9548A

Hello,

Can someone help with the difference between TCA9548AMRGER and TCA9548ARGER? I didn't see any mention in the datasheet or electrical specs. Only mention was a change in Oct 2015 "Added new orderable part number, TCA9548AMRGER"

    Hi Kyle,

    The part number with the "M" in it is rotated by 90 degrees in its packaging reel (compared to the "non-M" version). The two orderable part numbers exist only to give options to customers based on their manufacturing flow.

    Hi Kyle,

    To add to Max's response, the TCA9548AMRGER of the device has pin1 located in quadrant 1, as this can be a requirement by some factories. As mentioned, there are no changes to the IC besides the orientation. The TCA9848ARGER has pin1 located in quadrant 2.

    Regards,
