ISO7730DBQR from Texas Instruments, in a SSOP-16-150mil. 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 input for side 1, 2.25V to 5.5V recommended operating range. |
| 2 | GND1 | power_in | Ground reference for VCC1 on side 1. |
| 3 | INA | input | Channel A digital input; input high threshold ≥0.7×VCCI, input low threshold ≤0.3×VCCI. |
| 4 | INB | input | Channel B digital input; input high threshold ≥0.7×VCCI, input low threshold ≤0.3×VCCI. |
| 5 | INC | input | Channel C digital input; input high threshold ≥0.7×VCCI, input low threshold ≤0.3×VCCI. |
| 6 | NC | unconnected | No connection. |
| 7 | NC | unconnected | No connection. |
| 8 | GND1 | power_in | Ground reference for VCC1 on side 1. |
| 9 | GND2 | power_in | Ground reference for VCC2 on side 2. |
| 10 | EN2 | input | Output enable 2; high level or open circuit enables side 2 outputs OUTA/B/C, low level drives outputs to high impedance. |
| 11 | NC | unconnected | No connection. |
| 12 | OUTC | tri_state | Isolated output channel C; output high ≥VCCO-0.4V at -4mA, output low ≤0.4V at 4mA, high impedance when EN2=low. |
| 13 | OUTB | tri_state | Isolated output channel B; output high ≥VCCO-0.4V at -4mA, output low ≤0.4V at 4mA, high impedance when EN2=low. |
| 14 | OUTA | tri_state | Isolated output channel A; output high ≥VCCO-0.4V at -4mA, output low ≤0.4V at 4mA, high impedance when EN2=low. |
| 15 | GND2 | power_in | Ground reference for VCC2 on side 2. |
| 16 | VCC2 | power_in | Supply voltage input for side 2, 2.25V to 5.5V recommended operating range. |
