1 VIA Logic Input A. 2 VIB Logic Input B. 3, 81 VDD1 Input Supply Voltage, 4.5 V to 5.5 V. 4 GND1 Ground Reference for Input Logic Signals. 5 DISABLE Input Disable. Disables the isolator inputs and refresh circuits. Outputs take on default low state. 6, 7, 12, 132 NC No Connect. 9 GNDB Ground Reference for Output B. 10 VOB Output B. 11 VDDB Output B Supply Voltage, 12 V to 18 V. 14 GNDA Ground Reference for Output A. 15 VOA Output A. 16 VDDA Output A Supply Voltage, 12 V to 18 V. 1 Pin 3 and Pin 8 are internally connected. Connecting both pins to VDD1 is recommended. 2 Pin 12 and Pin 13 are floating and should be left unconnected.
