| 2 | GND1 | power_in | Ground connection for VCC1 side |
| 3 | INA | input | Channel A input, high-level ≥2 V, low-level ≤0.8 V, integrated noise filter |
| 4 | INB | input | Channel B input, high-level ≥2 V, low-level ≤0.8 V, integrated noise filter |
| 5 | INC | input | Channel C input, high-level ≥2 V, low-level ≤0.8 V, integrated noise filter |
| 6 | IND | input | Channel D input, high-level ≥2 V, low-level ≤0.8 V, integrated noise filter |
| 7 | NC | unconnected | No connect, floating with no internal connection |
| 8 | GND1 | power_in | Ground connection for VCC1 side |
