ISO7742QDBQRQ1 from Texas Instruments, in a SSOP-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 (input side) power supply, operating range 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC1 and GND1. |
| 2 | GND1 | power_in | Ground connection for VCC1 (side 1 ground). |
| 3 | INA | input | Channel A logic input on side 1, with VIH of 0.7 × VCCI minimum and VIL of 0.3 × VCCI maximum. |
| 4 | INB | input | Channel B logic input on side 1, with VIH of 0.7 × VCCI minimum and VIL of 0.3 × VCCI maximum. |
| 5 | OUTC | output | Channel C output on side 1 for the reverse-direction channel of the ISO7742-Q1. |
| 6 | OUTD | output | Channel D output on side 1 for the reverse-direction channel of the ISO7742-Q1. |
| 7 | EN1 | input | Output enable for side 1: high or open enables the side 1 outputs, and low places them in high impedance. |
| 8 | GND1 | power_in | Ground connection for VCC1 (side 1 ground). |
| 9 | GND2 | power_in | Ground connection for VCC2 (side 2 ground). |
| 10 | EN2 | input | Output enable for side 2: high or open enables the side 2 outputs, and low places them in high impedance. |
| 11 | IND | input | Channel D logic input on side 2 for the reverse-direction channel of the ISO7742-Q1. |
| 12 | INC | input | Channel C logic input on side 2 for the reverse-direction channel of the ISO7742-Q1. |
| 13 | OUTB | output | Channel B output on side 2 for the forward-direction channel of the ISO7742-Q1. |
| 14 | OUTA | output | Channel A output on side 2 for the forward-direction channel of the ISO7742-Q1. |
| 15 | GND2 | power_in | Ground connection for VCC2 (side 2 ground). |
| 16 | VCC2 | power_in | Side 2 (output side) power supply, operating range 2.25 V to 5.5 V, with a 0.1 µF decoupling capacitor recommended between VCC2 and GND2. |
