IX4340NTR from Littelfuse IXYS, in a SOIC-8. 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 | ENA | input | Enable input for Channel A; a logic high or floating input enables Channel A so OUTA follows INA, and a logic low holds OUTA low regardless of INA. |
| 2 | INA | input | Channel A logic input, internally pulled to GND, with input high threshold VIH minimum 2.5V and input low threshold VIL maximum 0.8V. |
| 3 | GND | power_in | Ground, the common ground reference for the device. |
| 4 | INB | input | Channel B logic input, internally pulled to GND, with input high threshold VIH minimum 2.5V and input low threshold VIL maximum 0.8V. |
| 5 | OUTB | output | Channel B output, capable of sourcing and sinking 5A peak current. |
| 6 | VCC | power_in | Supply voltage, specified for 5V to 20V operation with an absolute maximum rating of 20V, and under-voltage lockout keeps the outputs low below the UVLO threshold. |
| 7 | OUTA | output | Channel A output, capable of sourcing and sinking 5A peak current. |
| 8 | ENB | input | Enable input for Channel B; a logic high or floating input enables Channel B so OUTB follows INB, and a logic low holds OUTB low regardless of INB. |
