# HD3SS3202IRSVT

**Texas Instruments** · Analog Switches - Special Purpose · UQFN-16(1.8x2.6)

HD3SS3202IRSVT from Texas Instruments, in a UQFN-16(1.8x2.6). 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 | A0n | bidirectional | Port A channel 0 high-speed negative differential signal |

## CAD (KiCad official)

- Symbol: `HD3SS3202IRSVT`
- Footprint: `Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm`
- 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `hd3ss3202irsvt-etched.step` / `hd3ss3202irsvt-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `hd3ss3202irsvt.step` / `hd3ss3202irsvt.glb` are the bare package body.
