# IX4340NETR

**Littelfuse IXYS** · Gate Drivers · SOIC-8-EP

IX4340NETR from Littelfuse IXYS, in a SOIC-8-EP. 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) enables Channel A, and a logic low disables OUTA and holds it low regardless of INA. |
| 2 | INA | input | Channel A logic input, internally pulled to GND, with VIL maximum 0.8V and VIH minimum 2.5V at VCC=12V. |
| 3 | GND | power_in | Ground, the common ground reference for the device; the thermal pad may be connected to GND or left floating. |
| 4 | INB | input | Channel B logic input, internally pulled to GND, with VIL maximum 0.8V and VIH minimum 2.5V at VCC=12V. |
| 5 | OUTB | output | Channel B output, capable of sourcing and sinking 5A. |
| 6 | VCC | power_in | Supply voltage, specified for 5V to 20V operation with an absolute maximum rating of -0.3V to 20V. |
| 7 | OUTA | output | Channel A output, capable of sourcing and sinking 5A. |
| 8 | ENB | input | Enable input for Channel B; a logic high (or floating) enables Channel B, and a logic low disables OUTB and holds it low regardless of INB. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
