Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD1 | power_in | Supply voltage for isolator side 1; this pin requires a 0.1 µF bypass capacitor. |
| 2 | GND1 | power_in | Ground reference for isolator side 1. |
| 3 | VIA | input | Logic input A; per the truth table notes, input pins on a side with an unpowered supply must be held low to avoid powering the device through its ESD protection circuitry. |
| 4 | VIB | input | Logic input B; per the truth table notes, input pins on a side with an unpowered supply must be held low to avoid powering the device through its ESD protection circuitry. |
| 5 | VOC | output | Logic output C; it is enabled when VE2 is high or disconnected and is disabled to high-Z when VE2 is low. |
| 6 | VOD | output | Logic output D; it is enabled when VE2 is high or disconnected and is disabled to high-Z when VE2 is low. |
| 7 | VE1 | input | Output enable 1, active high logic input; when VE1 is high or disconnected the VOA and VOB outputs are enabled, and when low they are disabled to high-Z. |
| 8 | GND1 | power_in | Ground reference for isolator side 1. |
| 9 | GND2 | power_in | Ground reference for isolator side 2. |
| 10 | VE2 | input | Output enable 2, active high logic input; when VE2 is high or disconnected the VOC and VOD outputs are enabled, and when low they are disabled to high-Z. |
| 11 | VID | input | Logic input D; per the truth table notes, input pins on a side with an unpowered supply must be held low to avoid powering the device through its ESD protection circuitry. |
| 12 | VIC | input | Logic input C; per the truth table notes, input pins on a side with an unpowered supply must be held low to avoid powering the device through its ESD protection circuitry. |
| 13 | VOB | output | Logic output B; it is enabled when VE1 is high or disconnected and is disabled to high-Z when VE1 is low. |
| 14 | VOA | output | Logic output A; it is enabled when VE1 is high or disconnected and is disabled to high-Z when VE1 is low. |
| 15 | GND2 | power_in | Ground reference for isolator side 2. |
| 16 | VDD2 | power_in | Supply voltage for isolator side 2; this pin requires a 0.1 µF bypass capacitor. |
