Unable to convert ultrasonic sensor 5V echo to 3.3V using TXS0108E 8 Channel Logic Level Converter Bi-Directional
I’ve had nothing but trouble with bi-directional level shifters and would advise using unidirectional shifters whenever possible.  Bidirectional devices try to determine which side is driving and which is the load, but in my experience can easily be destabilised if the load side has any significant capacitance, which can cause it to present a low impedance when switching at high speed.
