SN74LVC1T45 Output

Other Parts Discussed in Thread: SN74LVC1T45

Hi,

I have a question regrading SN74LVC1T45 operation when there is no power input.

What is the output when VCCA and VCCB are both 0v ? Is the output 0v or floating?

Thanks,

Michael

    Hello Michael,

    From the data sheet, if both inputs are 0, then A and B outputs if DIR is high or low should be zero.

    If you apply a 0V to either VccA or VccB then both A and B will be in the high impedance state or Hi-Z.

    You should be able to simulate the circuit using the simulator found on the WeBench Page.

    Thanks,
