Can you tell me what the difference is between PN TLC393QDRG4 and TLC393QDRG4Q1.

Cheers

    Hi Calum,

    When I search on the TLC393QDRG4 model it is listed with our commercial grade version of the product. It is rated for -40 C to +125 C operation.

    Searching on the TLC393QDRG4Q1 lands on the automotive grade version of the product. The data sheet states that it is "Qualified for Automotive Applications." It too is rated for -40 C to +125 C operation.

    The intended use appears that is the primary difference.

    Calum,

      If you use ESP, go to each Product Folder page, the main parameters are shown and you can compare these side-by-side:

    In addition, the qualification testing is much more rigorous for automotive (-Q1) devices than for commercial (non -Q1) devices.  The tests typically have tighter specifications and have been tested 100% over temperature to meet the stringent needs for automotive devices.

    The Q1 device meets the requirements of AEC-Q100 through both "binning"and testing per AEC-Q100.

    http://focus.ti.com/download/auto/newsletters/autosolutions_04-09.htm provides a general explanation. See below:

    AEC-Q100 is an industry standard specification developed by major automotive manufacturers and suppliers, which outlines the recommended new product and major change qualification requirements and procedures. It details a set of stress tests, defines the minimum stress test driven qualification requirements, and references test conditions for the qualification of integrated circuits.

    Features:

    - Qualified at -40°C to 125°C (represented in the part number by the "Q" designator) —180-day PCN period versus standard 90-day PCN meets automotive minimum requirements

    - Q100 qualification data available on request —Single fab and A/T site help avoid shifts in performance or quality

    Hey Leonard,

    The specs above are the "best" case part - i.e. one that operates form 0C to 70C.

    If I go into both datasheets and look at the table for -40C to 125C I see no difference in parameters. This is a question form a CM who I believe is looking for a drop in replacement. Are the two parts the same silicon and just tested differently? as one is automotive only and the other covers the full -55C to 125C range?

    Cheers
