Tool/software:
We use level shift TXS0108EQPWRQ1 in ADAS product, which was monted in cars or buses.
In my design a MCU control the device via TXS0108, MCU is 3.3V system and device is 1.8V system. The device requires voltage low during boot procedure, we use a pull down resistor in level shift output pin.
B5 is measured with 3.3V, A5 is measured with 1.4V. OE is 1.72V
When i measured the level shift output pin A5 , the highl evel voltage is not 1.8V but 1.4V , some devices is only 1V, this means this level shift enter OD mode, i think this is the root cause of this failure.
In the TXS0108 datasheet, this level shift IC support push pull output. How could i set this level shift to push-pull mode?
