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

SN75372DR 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 | 1A | input | NAND input A for driver 1, with VIH of 2 V minimum and VIL of 0.8 V maximum; IIL is −1.6 mA maximum at 0.4 V. |
| 2 | E | input | Enable input shown in the schematic as common to both drivers, with VIH of 2 V minimum and VIL of 0.8 V maximum; IIL is −3.2 mA maximum at 0.4 V. |
| 3 | 2A | input | NAND input A for driver 2, with VIH of 2 V minimum and VIL of 0.8 V maximum; IIL is −1.6 mA maximum at 0.4 V. |
| 4 | GND | power_in | Network ground; all datasheet voltages are referenced to network GND. |
| 5 | VCC2 | power_in | Output-stage supply, 4.75 V to 24 V recommended, with a 25 V absolute maximum. |
| 6 | 2Y | output | Totem-pole output of driver 2, with a peak output current of 500 mA (tw < 10 ms, duty cycle < 50%) and a continuous IOL of 40 mA maximum. |
| 7 | 1Y | output | Totem-pole output of driver 1, with a peak output current of 500 mA (tw < 10 ms, duty cycle < 50%) and a continuous IOL of 40 mA maximum. |
| 8 | VCC1 | power_in | 5 V logic supply, 4.75 V to 5.25 V recommended, with a 7 V absolute maximum. |
