Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD1 | power_in | Supply voltage for isolator side 1; operating range 2.7 V to 5.5 V. |
| 2 | GND1 | power_in | Ground reference for isolator side 1; internally connected to pin 8 and both should be connected to GND1. |
| 3 | VIA | input | Logic input A accepting CMOS logic levels with high threshold 2.0 V (5V op) or 1.6 V (3V op) and low threshold 0.8 V (5V op) or 0.4 V (3V op). |
| 4 | VIB | input | Logic input B accepting CMOS logic levels with high threshold 2.0 V (5V op) or 1.6 V (3V op) and low threshold 0.8 V (5V op) or 0.4 V (3V op). |
| 5 | VIC | input | Logic input C accepting CMOS logic levels with high threshold 2.0 V (5V op) or 1.6 V (3V op) and low threshold 0.8 V (5V op) or 0.4 V (3V op). |
| 6 | VOD | tri_state | Logic output D providing isolated signal from VID input; output enabled when VE1 is high or floating, disabled to high impedance when VE1 is low. |
| 7 | VE1 | input | Output enable 1 (active high logic input) controlling VOD output; VOD enabled when high or floating, disabled when low. |
| 8 | GND1 | power_in | Ground reference for isolator side 1; internally connected to pin 2 and both should be connected to GND1. |
| 9 | GND2 | power_in | Ground reference for isolator side 2; internally connected to pin 15 and both should be connected to GND2. |
| 10 | VE2 | input | Output enable 2 (active high logic input) controlling VOA, VOB, VOC outputs; outputs enabled when high or floating, disabled when low. |
| 11 | VID | input | Logic input D accepting CMOS logic levels with high threshold 2.0 V (5V op) or 1.6 V (3V op) and low threshold 0.8 V (5V op) or 0.4 V (3V op). |
| 12 | VOC | tri_state | Logic output C providing isolated signal from VIC input; output enabled when VE2 is high or floating, disabled to high impedance when VE2 is low. |
| 13 | VOB | tri_state | Logic output B providing isolated signal from VIB input; output enabled when VE2 is high or floating, disabled to high impedance when VE2 is low. |
| 14 | VOA | tri_state | Logic output A providing isolated signal from VIA input; output enabled when VE2 is high or floating, disabled to high impedance when VE2 is low. |
| 15 | GND2 | power_in | Ground reference for isolator side 2; internally connected to pin 9 and both should be connected to GND2. |
| 16 | VDD2 | power_in | Supply voltage for isolator side 2; operating range 2.7 V to 5.5 V. |
