# DIO2561SC5

**DIOO** · Video Amplifiers · SC-70-5

DIO2561SC5 from DIOO, in a SC-70-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | input | Video input. Accepts AC- or DC-coupled composite/SD video. Input voltage range GND to 1.4 VPP; internal transparent clamp biases AC-coupled inputs. |
| 2 | GND | power_in | Ground reference for the supply and signal path. |
| 3 | VCC | power_in | Power supply input, 3.135 V to 5.5 V single supply. Typical supply current 8 mA. |
| 4 | GND | power_in | Ground reference for the supply and signal path. |
| 5 | VOUT | output | Filtered SD video output with 6 dB driver gain. Drives AC- or DC-coupled single (150Ω) or dual (75Ω) video loads. |

## CAD (KiCad official)

- Symbol: `DIO2561SC5`
- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`
- 3D model: SC-70-5 (KiCad packages3D, STEP)
- 3D model files: `dio2561sc5-etched.step` / `dio2561sc5-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `dio2561sc5.step` / `dio2561sc5.glb` are the bare package body.
