LM2903: Footprint compatible alternative with 4V switching threshold

Part Number: LM2903
Other Parts Discussed in Thread: LMV393

Hi team,

Do we have a footprint compatible alternative for LM2903 (TSSOP8) with a max switching threshold of 4.0V instead of 4.0V?

Thank you,

Franz

    Franz, 

    To clarify, do you mean to power your comparator at Vs = 5V? Therefore the upper bound of the common mode range for the LM2903 would be 3V. However you are looking for a pin to pin compatible device that would support a common mode of 4V at Vs = 5V?

    If you are powering the device at 5V, the LMV393 is a pin compatible device. At Vs = 5V, the common mode range extends to 4.2V.

    Regards,
    Jonny
