Original question:

TLV1701: datasheet specification

TLV1701: output capability for Driving 3.3V CMOS logic

Part Number: TLV1701

Hi Team,

According to the discussion in following thread, it looks TLV1701 can drive 3.3V CMOS logic properly if pull-up is smaller than 1kohm. But datasheet spec is too flexible to judge if it is possible or not. I'm just looking for low power comparator and TLV1701 looks good without the spec.

Then I have a coupe of questions to make it clear.

Can I confirm the progress of the request above? The lol vs Vol redone curves will definitely help for my business.
>We have put in a request to have these curves redone. I do not have a timeframe for that to occur at this point. 

Eventually, Does VOL swing depend on Vs voltage level? or Right date below is correct?
You showed two different results in the past thread as followings. so I'm confused.  

Regards,

Takashi Onawa

    Hello Takashi-san,

    The second graph is the better graph. The first graph was inferred from a few data points. Please use the second graph.

    By smaller, I assume you mean >1k. 1k would be 3.3mA sinking when "low", which seems a bit much for a 3.3V logic system. Unless you need the fastest rise-time into a large capacitive load, that is a lot of power to burn.

    We still have the full curves request in...releasing devices have priority...it is still on the back burner. But the second "large" graph does show very little variation in output drive over supply voltage.

    Allowing for temperature, I would keep the load below 2mA to keep well clear of the 0.5V VOL / 0.8V VIL limit.

    Hi Paul-san,

    Thanks, I understood.
