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 | TXD | input | Transmit Data Input from the CAN controller to the transceiver. Internally pulled up to VIO (which is internally tied to VCC on ATA6560). Dominant time-out disables the driver if held low longer than t_to(dom)TXD. |+| 2 | GND | power_in | Ground supply reference (0 V). |+| 3 | VCC | power_in | Supply voltage for the transceiver, 4.5 V to 5.5 V nominal. On ATA6560 the VCC and internal VIO rails are internally connected, so I/O levels are 5 V-compatible. |+| 4 | RXD | output | Receive Data Output; reads out data from the CAN bus lines. Push-pull output referenced to VIO/VCC. Recessive = HIGH, dominant = LOW; also signals wake-up requests in Standby mode. |+| 5 | NSIL | input | Silent Mode Control Input (low active). Together with STBY selects Silent (receive-only) mode. Internally pulled up to VIO/VCC. |+| 6 | CANL | bidirectional | Low-level CAN bus line. Differential I/O with CANH, driven low in dominant state and biased to VCC/2 in Normal mode. Short-circuit protected to GND or a positive supply, with ISO 7637-part-2 transient tolerance -150 V to +100 V and ±8 kV ESD (IEC 61000-4-2). |+| 7 | CANH | bidirectional | High-level CAN bus line. Differential I/O with CANL, driven high in dominant state and biased to VCC/2 in Normal mode. Short-circuit protected, with ISO 7637-part-2 transient tolerance -150 V to +100 V and ±8 kV ESD (IEC 61000-4-2). |+| 8 | STBY | input | Standby Mode Control Input. HIGH selects Standby (low-power) mode; LOW together with the appropriate NSIL/TXD state selects Normal or Silent operation. Internally pulled up to VIO/VCC. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `ATA6561-GAQW`+- `ATA6561-GAQW-N`+- `ATA6561-GAQWGBQW`+- `ATA6561-GAQWGBQW-N`+- `ATA6561-GAQWATA6561-GBQW`+- `ATA6561-GAQWATA6561-GBQW-N`++## CAD (KiCad official)++- Symbol: `ATA6561-GAQW`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip datasheet](docs/ata6561-gaqw-datasheet.pdf) (28 pp, sha256 `dac60589c9c1902e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
