ISO6741FQDWRQ1 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 | Side-1 power supply; VCC1 operates from 1.71 V to 1.89 V or 2.25 V to 5.5 V and needs a 0.1 µF decoupling capacitor to GND1 placed within 2 mm of the pin. |
| 2 | GND1 | power_in | Side-1 ground connection, the ground reference for VCC1 and the side-1 inputs and enable. |
| 3 | INA | input | Side-1 logic input for forward channel A, referenced to VCCI and GND1. |
| 4 | INB | input | Side-1 logic input for forward channel B, referenced to VCCI and GND1. |
| 5 | INC | input | Side-1 logic input for forward channel C, referenced to VCCI and GND1. |
| 6 | OUTD | output | Side-2 output of reverse channel D; it drives the output state from the isolated side-1 signal and goes high-impedance when EN2 is low. |
| 7 | EN1 | input | Side-1 output enable; driving EN1 high or leaving it open enables the side-1 outputs, and driving it low forces them to high-impedance. |
| 8 | GND1 | power_in | Side-1 ground connection, the ground reference for VCC1 and the side-1 inputs and enable. |
| 9 | GND2 | power_in | Side-2 ground connection, the ground reference for VCC2 and the side-2 outputs and enable. |
| 10 | EN2 | input | Side-2 output enable; driving EN2 high or leaving it open enables the side-2 outputs, and driving it low forces them to high-impedance. |
| 11 | IND | input | Side-1 logic input for reverse channel D, referenced to VCCI and GND1. |
| 12 | OUTC | output | Side-2 output for forward channel C, which defaults high on loss of input power for non-F devices. |
| 13 | OUTB | output | Side-2 output for forward channel B, which defaults high on loss of input power for non-F devices. |
| 14 | OUTA | output | Side-2 output for forward channel A, which defaults high on loss of input power for non-F devices. |
| 15 | GND2 | power_in | Side-2 ground connection, the ground reference for VCC2 and the side-2 outputs and enable. |
| 16 | VCC2 | power_in | Side-2 power supply; VCC2 operates from 1.71 V to 1.89 V or 2.25 V to 5.5 V and needs a 0.1 µF decoupling capacitor to GND2 placed within 2 mm of the pin. |
