ISO7841FDWW from Texas Instruments, in a SOIC-16-300mil. 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 | Power supply for side 1 (input side); recommended supply range is 2.25 V to 5.5 V. |
| 2 | GND1 | power_in | Ground connection for VCC1; this is the local ground reference for side 1 voltages. |
| 3 | INA | input | Input, channel A; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI. |
| 4 | INB | input | Input, channel B; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI. |
| 5 | INC | input | Input, channel C; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI. |
| 6 | OUTD | output | Output, channel D; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V. |
| 7 | EN1 | input | Output enable 1; side-1 outputs are enabled when EN1 is high or open and are high-impedance when EN1 is low. |
| 8 | GND1 | power_in | Ground connection for VCC1; this is the local ground reference for side 1 voltages. |
| 9 | GND2 | power_in | Ground connection for VCC2; this is the local ground reference for side 2 voltages. |
| 10 | EN2 | input | Output enable 2; side-2 outputs are enabled when EN2 is high or open and are high-impedance when EN2 is low. |
| 11 | IND | input | Input, channel D; logic high requires at least 0.7 × VCCI and logic low is at most 0.3 × VCCI. |
| 12 | OUTC | output | Output, channel C; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V. |
| 13 | OUTB | output | Output, channel B; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V. |
| 14 | OUTA | output | Output, channel A; output drive is limited to ±4 mA at VCCO = 5 V, ±2 mA at 3.3 V and ±1 mA at 2.5 V. |
| 15 | GND2 | power_in | Ground connection for VCC2; this is the local ground reference for side 2 voltages. |
| 16 | VCC2 | power_in | Power supply for side 2 (output side); recommended supply range is 2.25 V to 5.5 V. |
