ISO7842FDWWR 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 | Supply voltage for input-side channels, 2.25V to 5.5V operating range |
| 2 | GND1 | power_in | Ground connection for VCC1 |
| 3 | INA | input | Input for channel A |
| 4 | INB | input | Input for channel B |
| 5 | OUTC | tri_state | Output for channel C; transmits logic state of INC when EN1 is high or open, high-impedance when EN1 is low |
| 6 | OUTD | tri_state | Output for channel D; transmits logic state of IND when EN1 is high or open, high-impedance when EN1 is low |
| 7 | EN1 | input | Output enable for side 1; high or open enables OUTC and OUTD pins, low results in high-impedance state |
| 8 | GND1 | power_in | Ground connection for VCC1 |
| 9 | GND2 | power_in | Ground connection for VCC2 |
| 10 | EN2 | input | Output enable for side 2; high or open enables OUTA and OUTB pins, low results in high-impedance state |
| 11 | IND | input | Input for channel D |
| 12 | INC | input | Input for channel C |
| 13 | OUTB | tri_state | Output for channel B; transmits logic state of INB when EN2 is high or open, high-impedance when EN2 is low |
| 14 | OUTA | tri_state | Output for channel A; transmits logic state of INA when EN2 is high or open, high-impedance when EN2 is low |
| 15 | GND2 | power_in | Ground connection for VCC2 |
| 16 | VCC2 | power_in | Supply voltage for output-side channels, 2.25V to 5.5V operating range |
