Texas Instruments · Digital Isolators · SSOP-16-150mil
ISO7742FDBQR from Texas Instruments, in a SSOP-16-150mil. 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 | Primary-side supply voltage, rated 2.25V to 5.5V |
| 2 | GND1 | power_in | Primary-side ground reference for VCC1 |
| 3 | INA | input | Channel A digital input, primary side, accepts logic levels from 0V to VCCI |
| 4 | INB | input | Channel B digital input, primary side, accepts logic levels from 0V to VCCI |
| 5 | OUTC | output | Channel C digital output, secondary side, provides logic levels 0V to VCCO, reverse channel |
| 6 | OUTD | output | Channel D digital output, secondary side, provides logic levels 0V to VCCO, reverse channel |
| 7 | EN1 | input | Primary-side output enable; high or open enables channel outputs, low places outputs in high-impedance state |
| 8 | GND1 | power_in | Primary-side ground reference for VCC1 |
| 9 | GND2 | power_in | Secondary-side ground reference for VCC2 |
| 10 | EN2 | input | Secondary-side output enable; high or open enables channel outputs, low places outputs in high-impedance state |
| 11 | IND | input | Channel D digital input, primary side, accepts logic levels from 0V to VCCI, reverse channel |
| 12 | INC | input | Channel C digital input, primary side, accepts logic levels from 0V to VCCI, reverse channel |
| 13 | OUTB | output | Channel B digital output, secondary side, provides logic levels 0V to VCCO, forward channel |
| 14 | OUTA | output | Channel A digital output, secondary side, provides logic levels 0V to VCCO, forward channel |
| 15 | GND2 | power_in | Secondary-side ground reference for VCC2 |
| 16 | VCC2 | power_in | Secondary-side supply voltage, rated 2.25V to 5.5V |
