ISO7342CDWR from Texas Instruments, in a SOIC-16-300mil. 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 input-side isolation barrier; 3-5.5V recommended operating range |
| 2 | GND1 | power_in | Ground connection for input-side power supply VCC1 |
| 3 | INA | input | Channel A input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds |
| 4 | INB | input | Channel B input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds |
| 5 | OUTC | output | Channel C output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply |
| 6 | OUTD | output | Channel D output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply |
| 7 | EN1 | input | Output enable 1 for side-1 outputs; high or disconnected enables outputs, low disables to high-impedance |
| 8 | GND1 | power_in | Ground connection for input-side power supply VCC1 |
| 9 | GND2 | power_in | Ground connection for output-side power supply VCC2 |
| 10 | EN2 | input | Output enable 2 for side-2 outputs; high or disconnected enables outputs, low disables to high-impedance |
| 11 | IND | input | Channel D input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds |
| 12 | INC | input | Channel C input with integrated noise filter; 2-5.5V high-level, 0-0.8V low-level thresholds |
| 13 | OUTB | output | Channel B output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply |
| 14 | OUTA | output | Channel A output; high-level VCCO-0.5V to 5V typical, low-level 0-0.4V at 5V supply |
| 15 | GND2 | power_in | Ground connection for output-side power supply VCC2 |
| 16 | VCC2 | power_in | Power supply for output-side isolation barrier; 3-5.5V recommended operating range |
