SN74LVC1G32: SN74LVC1G32

Part Number: SN74LVC1G32

Dear SIR:

May I have some question regarding SN74LVC1G32

The question is "How to know that is push pull or Open Drain or...type output component by what's information from SN74LVC1G32 datasheet ?"

As we know that "SN74LVC1G07 have mention SN74LVC1G07 is Open drain output component from datasheet" ,But How about  SN74LVC1G32 ?

Thanks

  • Hi Alex,

    This device is not open-drain. A few ways to tell: the datasheet will explicitly state that the device is open-drain, you will most likely see an open-drain symbol, the spec table won't have VOH specs.

    Dear SIR:

    Thanks for your reply.

    May I have another question regarding How to get the SN74LVC1G32 Max power consumption ?

    Would you have any example for reference ?

    Thanks

  • In reply to TAlex Wu:

    Hi Alex,

    I do indeed have a great reference for you. Please check out the application report below:

    Dear SIR:

    Thanks for your reply.

    May I double confirming ,What's Max operating current(current consumption )  from SN74LVC1G32 datasheet ?

    Thanks

  • In reply to TAlex Wu:

    Hi Alex,

    The spec you want to use is the Icc spec which is 10 uA max.

    Dear SIR:

    Thanks for your reply.

    May I double confirming regarding "If Icc MAX =10uA",Why datasheet Application Curves mention "Icc-mA" ?

    Thanks 

  • In reply to TAlex Wu:

    Hi Alex,

    The application curve shows when the device is driving a load at certain frequencies. The spec is a static Icc equivalent to quiescent current.

    Dear SIR:
    Thank for your reply.
    For our question "What's Max operating current(current consumption ) from SN74LVC1G32 datasheet ?"
    As you reply that " Icc spec which is 10 uA max and spec is a static Icc equivalent to quiescent current"
    Is that your meaning 10 uA max is a static Icc MAX ( for Static power consumption) and the application curve shows "mA"Icc is Dynamic
    (for Dynamic power consumption)?
    For above,"What's Max operating current(current consumption )for Icc is Dynamic from SN74LVC1G32 datasheet ?"

    Thanks
  • In reply to TAlex Wu:

    Hi Alex,

    Dynamic Icc is dependent on how the device is operating and there is no spec for that. If you power the device without any operation your max power consumption is 10 uA. That application report I linked before should highlight the differences between the two.
