| 2 | GND1 | power_in | Ground connection for VCC1 |
| 3 | INA | input | Isolated input channel A with integrated noise filter, TTL-compatible threshold |
| 4 | INB | input | Isolated input channel B with integrated noise filter, TTL-compatible threshold |
| 5 | OUTC | tri_state | Isolated inverted output channel C, tri-state disabled to high-Z when EN2 is low |
| 6 | OUTD | tri_state | Isolated inverted output channel D, tri-state disabled to high-Z when EN2 is low |
| 7 | EN1 | input | Output enable 1 for channels A and B, enables when high or disconnected, disables when low |
| 8 | GND1 | power_in | Ground connection for VCC1 |
| 9 | GND2 | power_in | Ground connection for VCC2 |
| 10 | EN2 | input | Output enable 2 for channels C and D, enables when high or disconnected, disables when low |
| 11 | IND | input | Isolated input channel D with integrated noise filter, TTL-compatible threshold |
| 12 | INC | input | Isolated input channel C with integrated noise filter, TTL-compatible threshold |
| 13 | OUTB | tri_state | Isolated non-inverted output channel B, tri-state disabled to high-Z when EN1 is low |
| 14 | OUTA | tri_state | Isolated non-inverted output channel A, tri-state disabled to high-Z when EN1 is low |
| 15 | GND2 | power_in | Ground connection for VCC2 |
| 16 | VCC2 | power_in | Power supply voltage (VCCO) for output-side circuits, 3 to 5.5 V range |
