SN74AVC2T244: supply current when VCCA = 3.3V, VCCB =0V

Part Number: SN74AVC2T244


We have one use case of SN74AVC2T244, VCCA = 3.3V, VCCB =0V, direction from A to B, and OE = 1, in this condition, how about the supply current and leakage current, thanks.

  • Hi Jun,

    The input leakage current doesn't have any dependence on the output supply voltage, it will still be 1.5 uA max.

    The output leakage is also 1.5 uA in this circumstance.

    The supply current is dependent on the input conditions. If all inputs are held at the rails (0V or Vcca), then IccA can be up to 3uA max.
