SN74LVC1G11-EP: SN74LVC1G11-EP

Part Number: SN74LVC1G11-EP

Hello,

 

We  are using SINGLE 3-INPUT POSITIVE AND GATE SN74LVC1G11-EP. And we need to ensure that its output stays at 0 during power up and power down.

During power up, can the output be momentarily driven high by the IC ? Up to what voltage ?

Would a pull down keep the output low and avoid this issue ?

During power down, can the output be momentarily driven high by the IC ? Up to what voltage ?

Would a pull down keep the output low and avoid this issue ?

 

Thanks and regards,

Annaïs

  • Hi,

    During power up, can the output be momentarily driven high by the IC ? Up to what voltage ?

    Yes, this could be the case, the datasheet does not guarantee output condition during powerup. The output voltage will be the same as the VCC voltage.

    Would a pull down keep the output low and avoid this issue ?

    If the device tries to drive the output high, it will do so. There is no enable pin on this device to keep the output in Hi-Z

    During power down, can the output be momentarily driven high by the IC ? Up to what voltage ?

    Similar to power up, there can be a change on the output depending on the Vcc voltage. If Vcc is 1.65 for example, then output will be 1.65.

    Thanks!
