ISO7742FQDWQ1 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 supply voltage, recommended range 2.25 V to 5.5 V, decoupled with a 0.1 µF capacitor to GND1 placed no more than 2 mm from the pin. |
| 2 | GND1 | power_in | Side-1 ground connection for VCC1 (pins 2 and 8 are both side-1 ground). |
| 3 | INA | input | Logic input, channel A on side 1; VIH is 0.7 x VCCI minimum and VIL is 0.3 x VCCI maximum. |
| 4 | INB | input | Logic input, channel B on side 1; VIH is 0.7 x VCCI minimum and VIL is 0.3 x VCCI maximum. |
| 5 | OUTC | output | Output of channel C; follows the logic state of its input and goes high impedance when the enable pin is low. |
| 6 | OUTD | output | Output of channel D; follows the logic state of its input and goes high impedance when the enable pin is low. |
| 7 | EN1 | input | Output enable for side 1; side-1 outputs are enabled when EN1 is high or open and go to high impedance when EN1 is low. |
| 8 | GND1 | power_in | Side-1 ground connection for VCC1 (second side-1 ground pin, with pin 2). |
| 9 | GND2 | power_in | Side-2 ground connection for VCC2 (pins 9 and 15 are both side-2 ground). |
| 10 | EN2 | input | Output enable for side 2; side-2 outputs are enabled when EN2 is high or open and go to high impedance when EN2 is low. |
| 11 | IND | input | Logic input, channel D on side 2; VIH is 0.7 x VCCI minimum and VIL is 0.3 x VCCI maximum. |
| 12 | INC | input | Logic input, channel C on side 2; VIH is 0.7 x VCCI minimum and VIL is 0.3 x VCCI maximum. |
| 13 | OUTB | output | Output of channel B; follows the logic state of its input and goes high impedance when the enable pin is low. |
| 14 | OUTA | output | Output of channel A; follows the logic state of its input and goes high impedance when the enable pin is low. |
| 15 | GND2 | power_in | Side-2 ground connection for VCC2 (second side-2 ground pin, with pin 9). |
| 16 | VCC2 | power_in | Side-2 supply voltage, recommended range 2.25 V to 5.5 V, decoupled with a 0.1 µF capacitor to GND2 placed no more than 2 mm from the pin. |
