Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD1 | power_in | Power supply for isolator side 1, specified at 2.5 V to 5.5 V, with a 0.1 µF bypass capacitor to GND1 placed as close to the package as possible. |
| 2 | INA | input | Logic input A referenced to GND1; VIH is at least 2 V and VIL at most 0.8 V, and the input must stay between -0.4 V and VDD+0.4 V with an absolute maximum of 6.5 V. |
| 3 | OUTB | output | Logic output B; VOH is at least VDD−0.4 V at IOH ≤ 4 mA and VOL is at most 0.4 V at IOL ≤ 4 mA, with output current limited to ±15 mA absolute maximum. |
| 4 | GND1 | power_in | Ground 1, the ground reference for isolator side 1. |
| 5 | GND2 | power_in | Ground 2, the ground reference for isolator side 2. |
| 6 | INB | input | Logic input B; VIH is at least 2 V and VIL at most 0.8 V, and the input must stay between -0.4 V and VDD+0.4 V with an absolute maximum of 6.5 V. |
| 7 | OUTA | output | Logic output A; VOH is at least VDD−0.4 V at IOH ≤ 4 mA and VOL is at most 0.4 V at IOL ≤ 4 mA, with output current limited to ±15 mA absolute maximum. |
| 8 | VDD2 | power_in | Power supply for isolator side 2, specified at 2.5 V to 5.5 V, with a 0.1 µF bypass capacitor to GND2 placed as close to the package as possible. |
