FAQ: Logic and Voltage Translation > Auto-Bidirectional Level-Shifters >> Current FAQ
To mitigate oscillation concerns with devices with edge rate accelerators / one-shots such as TXB / TXS devices, consider below:
- Short enough traces for round-trip delay reflections within the one-shot duration of 10-30 ns. See data sheets.
- Tolerances of any additional RC components, similar to the data sheet recommendations
- Utilizing fast enough input edges per the input transition rate
- < 70 pF lumped capacitive loading. This includes additional parasitic capacitance from long trace lengths and connectors.
- Minimizing reflections with series dampening resistors on the outputs. See [FAQ] Can I estimate appropriate dampening resistor value for level-shifter outputs?
