Hello,
I'm looking for some clarification on the LSF0108 level shifter. Specifically, I'd like to know if the A-side inputs LMK_PDN, LMK_REFSEL, and LMK_HW_SW_CTRL on my schematic require pull-ups since they are push-pull signals (while LMK_STATUS0/1 and LMK_SDA/SCL are open-drain).
The datasheet is ambiguous in section 9.2.4, as we are in the case where Vref_B = Vref_A + 0.8 V (here we have Vref_B = 3.3 V and Vref_A = 2.5 V). In addition, I'd like to know if pull-ups are required for the B-side inputs. Although the datasheet paragraph doesn't mention it, figure 9.6 suggests the use of pull-ups.
Thank you
