ISO7240CDWR 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 | Primary side power supply input; operates from 3.15V to 5.5V |
| 2 | GND1 | power_in | Ground reference for primary side |
| 3 | INA | input | Input channel A from primary side |
| 4 | INB | input | Input channel B from primary side |
| 5 | INC | input | Input channel C from primary side |
| 6 | IND | input | Input channel D from primary side |
| 7 | NC | unconnected | No connection pin; not connected internally |
| 8 | GND1 | power_in | Ground reference for primary side |
| 9 | GND2 | power_in | Ground reference for secondary side |
| 10 | EN | input | Output enable control; high or open enables all outputs; low forces outputs to high-impedance |
| 11 | OUTD | tri_state | Output channel D to secondary side; tri-state controlled by EN pin |
| 12 | OUTC | tri_state | Output channel C to secondary side; tri-state controlled by EN pin |
| 13 | OUTB | tri_state | Output channel B to secondary side; tri-state controlled by EN pin |
| 14 | OUTA | tri_state | Output channel A to secondary side; tri-state controlled by EN pin |
| 15 | GND2 | power_in | Ground reference for secondary side |
| 16 | VCC2 | power_in | Secondary side power supply input; operates from 3.15V to 5.5V |
