LM2901: LM2901 vs TLV1704

LM2901: LM2901 vs TLV1704

Part Number: LM2901


Dear Paul, thank you
I'd like to replace LM339(LM2901) by TLV1704.
You mean that all comparators: LM339, LM393, TLV1704 have equal logic?

TIA

Sincerely,

Vladimir Naumenkov

    Hello Valdmir,

    Yes. All comparators follow the same logic.

    +IN > -IN = Output High
    +IN < -IN = Output Low

    Bringing the negative input higher than the positive output will make the output go "low", or pulling to ground (output transistor conducting to GND).

    Bringing the positive input higher than the negative input will make the output go "high", or not conducting (output pulled high by the pull-up resistor).
