ISO7840DWR from Texas Instruments, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VCC1 | power_in | Input side power supply, recommended operating range 2.25V to 5.5V. |
| 2 | GND1 | power_in | Input side ground reference for VCC1. |
| 3 | INA | input | Channel A input signal, logic levels referenced to VCCI. |
| 4 | INB | input | Channel B input signal, logic levels referenced to VCCI. |
| 5 | INC | input | Channel C input signal, logic levels referenced to VCCI. |
| 6 | IND | input | Channel D input signal, logic levels referenced to VCCI. |
| 7 | NC | unconnected | No internal connection; leave unconnected. |
| 8 | GND1 | power_in | Input side ground reference for VCC1. |
| 9 | GND2 | power_in | Output side ground reference for VCC2. |
| 10 | EN2 | input | Output enable for side 2; when high or open, outputs enabled; when low, outputs in high impedance state. |
| 11 | OUTD | output | Channel D output signal, logic levels referenced to VCCO. |
| 12 | OUTC | output | Channel C output signal, logic levels referenced to VCCO. |
| 13 | OUTB | output | Channel B output signal, logic levels referenced to VCCO. |
| 14 | OUTA | output | Channel A output signal, logic levels referenced to VCCO. |
| 15 | GND2 | power_in | Output side ground reference for VCC2. |
| 16 | VCC2 | power_in | Output side power supply, recommended operating range 2.25V to 5.5V. |
