Description
Supply Voltage A for Isolator Side 1 (3.0 V to 5.5 V). Pin 1 must be connected externally to Pin 7. Connect a ceramic
bypass capacitor of value 0.01 μF to 0.1 μF between V DD1A (Pin 1) and GND 1 (Pin 2).
Ground 1. Ground reference for Isolator Side 1. Pin 2 and Pin 8 are internally connected, and connecting both to GND 1 is
recommended.
