  • TXB0304: The internal circuit of the TXB0304 chip passes through a 1K resistor and then outputs it, causing an impedance mismatch in the high-speed circuit.

    Part Number: TXB0304 Other Parts Discussed in Thread: TXU0304 , TXU0104 , TXU0204 The internal circuit output of the TXB0304 chip needs to pass through a 1K resistor, which will cause a resistor-impedance mismatch during high-speed signal conversion,…

  • [FAQ] TXB0304 oscillates but TXB0104 works, why?

    Other Parts Discussed in Thread: TXB0304 , TXB0104 FAQ: Logic and Voltage Translation > Auto-Bidirectional Level-Shifters >> Current FAQ The most common reason is due to impedance mismatches. TXB0304 specifies a stronger output impedance than TXB0104…
