PCA9306は、電圧レベルシフト機能を有していますが、
入力電圧レベル3.3Vをレベルシフトせずに、
出力電圧3.3Vにすることは可能ですか？

This is possible. The pull-up voltage at the data I/O pins is not required to be the same as V_REF1/V_REF2. The only restriction is that V_REF1 is the lowest voltage.

Hello,

PCA9306 can be used when VREF1 = VREF2. If controlling the enable pin via GPIO, please make sure that GPIO voltage does not exceed VREF2 + VTH.
