# ISO6741QDWRQ1

**TEXAS INSTRUMENTS** · Global Sourcing Parts · SOIC-16

ISO6741QDWRQ1 from TEXAS INSTRUMENTS, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Power supply for side 1, which may be 1.71 V to 1.89 V or 2.25 V to 5.5 V per the recommended operating conditions. |
| 2 | GND1 | power_in | Ground connection for VCC1 on side 1. |
| 3 | INA | input | Input for channel A, referenced to side 1 ground. |
| 4 | INB | input | Input for channel B, referenced to side 1 ground. |
| 5 | INC | input | Input for channel C, referenced to side 1 ground. |
| 6 | OUTD | output | Output for channel D, which is the reverse-direction channel on the ISO6741-Q1. |
| 7 | EN1 | input | Output enable for side 1: a high or open level enables the side 1 outputs, and a low level forces them to high impedance. |
| 8 | GND1 | power_in | Ground connection for VCC1 on side 1. |
| 9 | GND2 | power_in | Ground connection for VCC2 on side 2. |
| 10 | EN2 | input | Output enable for side 2: a high or open level enables the side 2 outputs, and a low level forces them to high impedance. |
| 11 | IND | input | Input for channel D, which is the reverse-direction channel on the ISO6741-Q1. |
| 12 | OUTC | output | Output for channel C, referenced to side 2 ground. |
| 13 | OUTB | output | Output for channel B, referenced to side 2 ground. |
| 14 | OUTA | output | Output for channel A, referenced to side 2 ground. |
| 15 | GND2 | power_in | Ground connection for VCC2 on side 2. |
| 16 | VCC2 | power_in | Power supply for side 2, which may be 1.71 V to 1.89 V or 2.25 V to 5.5 V per the recommended operating conditions. |
