2.2.1 Biasing Requirements

  • TXB or TXS: Make sure supply voltages match data sheet recommendations for VCCA ≤ VCCB.
  • LSF: Make sure supply voltages match data sheet recommendations for Vref_B ≥ Vref_A + 0.8V.
    • If level-shifting voltage levels conflicting with the above for LSF, pull-ups to voltage supplies different from Vref can be populated on the inputs or outputs.
    • If LDOs are used, make sure LDO used can sink current flowing from Vref_B into Vref_A. With the recommended LSF 200kΩ bias resistor, current = (Vref_B - Vref_A - 0.8V) / 200kΩ.
      • Or, a 100kΩ weak pull-down resistor on Vref_A to the output of the regulator is recommended.
