# UCC5304DWVR

**Texas Instruments** · Isolators - Gate Drivers · SOIC-8-300mil

UCC5304DWVR from Texas Instruments, in a SOIC-8-300mil. 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 | IN | input | Input signal with a TTL/CMOS compatible threshold; the pin is pulled low internally if left open, and tying it to ground is recommended when unused for better noise immunity. |
| 2 | VCCI | power_in | Primary-side supply voltage, recommended operating range 3 V to 5.5 V, locally decoupled to GND with a low ESR/ESL capacitor placed as close to the device as possible. |
| 3 | VCCI | power_in | Primary-side supply voltage (second VCCI pin), recommended operating range 3 V to 5.5 V, locally decoupled to GND with a low ESR/ESL capacitor placed as close to the device as possible. |
| 4 | GND | power_in | Primary-side ground reference; all signals on the primary side are referenced to this ground. |
| 5 | VSS | power_in | Ground for the secondary-side driver. |
| 6 | VSS | power_in | Ground for the secondary-side driver (second VSS pin). |
| 7 | OUT | output | Driver output, connected to the gate of the FET or IGBT; the output is referenced to VSS and must withstand the absolute maximum OUT to VSS range of -0.5 V to VVDD+0.5 V. |
| 8 | VDD | power_in | Secondary-side driver supply, recommended operating range 6 V to 18 V, locally decoupled to VSS with a low ESR/ESL capacitor placed as close to the device as possible. |
