Pinout

Pin Name Type Function
1 VDD1 power_in Supply voltage for isolator side 1 is 2.25 V to 3.6 V, with a ceramic bypass capacitor of 0.01 µF to 0.1 µF connected between VDD1 and GND1.
2 VOA output Logic Output A; per the truth tables, the VOx output goes high impedance when its output-side supply is unpowered.
3 VIB input Logic Input B; the datasheet specifies a logic high threshold of 0.7 VDDx1 and a logic low threshold of 0.3 VDDx1.
4 GND1 power_in Ground 1 is the ground reference for isolator side 1 and the return for the VDD1 bypass capacitor.
5 GND2 power_in Ground 2 is the ground reference for isolator side 2.
6 VOB output Logic Output B; per the truth tables, the VOx output goes high impedance when its output-side supply is unpowered.
7 VIA input Logic Input A; the datasheet specifies a logic high threshold of 0.7 VDDx1 and a logic low threshold of 0.3 VDDx1.
8 VDD2 power_in Supply voltage for isolator side 2 is 2.25 V to 3.6 V, with a ceramic bypass capacitor of 0.01 µF to 0.1 µF connected between VDD2 and GND2.
