    Having trouble. Trying to shift 1.8V signal to 5.0V.
    Problem is, when I wire the 1.8V + GND and the 5.0V + GND, the TXI pins go high to 1.8V, and the TXO’s go high to 5.0V, even though nothing is attached to the TXI pins (TXO’s are attached to signal pin of NPN collecting from the 5.0V supply)
    Any help would be appreciated.
    My 5.0V supply is 1000mA,
    and the 1.8V is ~ 150mA
    this is the schematic of what i’m doing:
