Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Power supply for input-side circuitry, operating voltage 3 to 5.5 V. |
| 2 | GND1 | power_in | Ground connection for VCC1 input-side supply. |
| 3 | INA | input | Input channel A with TTL-compatible thresholds VIH ≥ 2 V and VIL ≤ 0.8 V. |
| 4 | INB | input | Input channel B with TTL-compatible thresholds VIH ≥ 2 V and VIL ≤ 0.8 V. |
| 5 | OUTC | output | Output channel C (reverse direction) with VOH typical 4.7 V and VOL typical 0.4 V at 5 V supply. |
| 6 | OUTD | output | Output channel D (reverse direction) with VOH typical 4.7 V and VOL typical 0.4 V at 5 V supply. |
| 7 | EN1 | input | Output enable 1 with high-level threshold 2 V; enables output pins on side-1 when high or disconnected, disables when low. |
| 8 | GND1 | power_in | Ground connection for VCC1 input-side supply. |
| 9 | GND2 | power_in | Ground connection for VCC2 output-side supply. |
| 10 | EN2 | input | Output enable 2 with high-level threshold 2 V; enables output pins on side-2 when high or disconnected, disables when low. |
| 11 | IND | input | Input channel D (reverse direction) with TTL-compatible thresholds VIH ≥ 2 V and VIL ≤ 0.8 V. |
| 12 | INC | input | Input channel C (reverse direction) with TTL-compatible thresholds VIH ≥ 2 V and VIL ≤ 0.8 V. |
| 13 | OUTB | output | Output channel B (forward direction) with VOH typical 4.7 V and VOL typical 0.4 V at 5 V supply. |
| 14 | OUTA | output | Output channel A (forward direction) with VOH typical 4.7 V and VOL typical 0.4 V at 5 V supply. |
| 15 | GND2 | power_in | Ground connection for VCC2 output-side supply. |
| 16 | VCC2 | power_in | Power supply for output-side circuitry, operating voltage 3 to 5.5 V. |
