**Texas Instruments** · Gate Drivers · SOIC-8

LM5111-2MX from Texas Instruments, 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 | NC | unconnected | No Connection. |
| 2 | IN_A | input | 'A' side control input with TTL compatible thresholds. |
| 3 | VEE | power_in | Ground reference for both inputs and outputs. |
| 4 | IN_B | input | 'B' side control input with TTL compatible thresholds. |
| 5 | OUT_B | output | Output for the 'B' side driver with voltage swing from VCC to VEE, capable of sourcing 3 A and sinking 5 A. |
| 6 | VCC | power_in | Positive output supply; locally decouple to VEE. |
| 7 | OUT_A | output | Output for the 'A' side driver with voltage swing from VCC to VEE, capable of sourcing 3 A and sinking 5 A. |
| 8 | NC | unconnected | No Connection. |
