The level converter works, the board from the test stand in the photo. Analog txs0108. Side a connects to a lower voltage than side b. the oe output drawn to the gnd translates the chip's findings into a high impedance state, the state is used when starting devices. To transfer the level converter to the working state, the oe output is connected to the positive voltage of the side a. switching occurs on the front of the pulses. If there was zero and then the output disconnected, the opposite side of the output, has every chance to hang in an uncertain state about half of the power supply of this side. Therefore, for a clear switching, the output is the input to connect to the minus and the plus of the power supply of its side. In general, the chip works perfectly. I negotiated 3,3 v 5 v, so the figure shows such values. Packaging is strange, in plastic bags. Nevertheless, converters work, i recommend.
