    Hello Suma,

    Unfortunately, I do not see a Q1 version on the roadmap.

    What is the application? Could they use an open-collector output? Such as the LM211-Q1?

    Hello Paul,

    Good morning!

    I am looking for the automotive qualified part with fast response time like 60ns to 80ns. Dual power supply like input and out will have different power supply.

    Is there any plan in the next quart to qualify this part as automotive qualified part.

    Best Regards,

    Suma

    Hello Suma,

    At this point no, the TLV1871/2 are the only general purpose devices with P-P output with separate supplies.

    We do have the high speed TLV3801/2-Q1 that has separate output supplies, but the output is LVDS and 5V supply max.

    I have forwarded your posts the internal people that make the product decisions.  They may reach out to you for more details.

    Hi Suma,

    At this time, the TLV187x and TLV3801-Q1 are the only devices with separate output supplies. This is a fairly new product category.

    As mentioned above, the LM211-Q1 is the only Q1 device with a "floating" output, but it is a open collector output. Prop delay is about 170ns.

    Hi Suma,

    As Paul mentioned in the first response, the Q1 version of the TLV1872 isn't on the roadmap as of now.
