ISO7730FDWR 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 | Input side supply voltage with recommended operating range of 2.25V to 5.5V per Section 5.3. |
| 2 | GND1 | power_in | Ground connection for VCC1 input side per Table 4-1. |
| 3 | INA | input | Input channel A with switching threshold from 0.3×VCCI (low) to 0.7×VCCI (high) per Section 5.9. |
| 4 | INB | input | Input channel B with switching threshold from 0.3×VCCI (low) to 0.7×VCCI (high) per Section 5.9. |
| 5 | INC | input | Input channel C with switching threshold from 0.3×VCCI (low) to 0.7×VCCI (high) per Section 5.9. |
| 6 | NC | unconnected | Not connected; no electrical function per Table 4-1. |
| 7 | NC | unconnected | Not connected; no electrical function per Table 4-1. |
| 8 | GND1 | power_in | Ground connection for VCC1 input side per Table 4-1. |
| 9 | GND2 | power_in | Ground connection for VCC2 output side per Table 4-1. |
| 10 | EN2 | input | Output enable 2; high or open state enables side 2 outputs, low state places outputs in high impedance per Table 4-1. |
