Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC | power_in | Supply voltage input to primary side, recommended operating range 3V to 5.5V, powers primary side circuits and DC-DC converter. |
| 2 | GND1 | power_in | Ground connection for VCC supply. |
| 3 | INA | input | Input channel A, accepts CMOS logic levels with 0 to 0.3×VSI for low and 0.7×VSI to VSI for high. |
| 4 | INB | input | Input channel B, accepts CMOS logic levels with 0 to 0.3×VSI for low and 0.7×VSI to VSI for high. |
| 5 | INC | input | Input channel C, accepts CMOS logic levels with 0 to 0.3×VSI for low and 0.7×VSI to VSI for high. |
| 6 | OUTD | output | Output channel D, drives 0.2 to 0.4V low and VSO-0.2V high with ±4 mA drive capability at 5V output. |
| 7 | NC | unconnected | No connection. |
| 8 | GND1 | power_in | Ground connection for VCC supply. |
| 9 | GND2 | power_in | Ground connection for VISO isolated power supply. |
| 10 | SEL | input | VISO selection input; tie to VISO for 5V output, tie to GND2 or leave open for 3.3V output. |
| 11 | IND | input | Input channel D, accepts CMOS logic levels with 0 to 0.3×VSI for low and 0.7×VSI to VSI for high. |
| 12 | OUTC | output | Output channel C, drives 0.2 to 0.4V low and VSO-0.2V high with ±4 mA drive capability at 5V output. |
| 13 | OUTB | output | Output channel B, drives 0.2 to 0.4V low and VSO-0.2V high with ±4 mA drive capability at 5V output. |
| 14 | OUTA | output | Output channel A, drives 0.2 to 0.4V low and VSO-0.2V high with ±4 mA drive capability at 5V output. |
| 15 | GND2 | power_in | Ground connection for VISO isolated power supply. |
| 16 | VISO | power_out | Isolated power supply output, 3.3V or 5V selectable via SEL pin, capable of supplying up to 130 mA to isolated side loads. |
