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 protocol controller. A logic-low on TXD drives the bus to the dominant state; a logic-high (or floating) allows the bus to relax to recessive. CMOS-compatible input referenced to VDD (5 V nominal). |+| 2 | VSS | power_in | Ground reference (0 V) for the transceiver. Connect to the system ground plane close to the device. |+| 3 | VDD | power_in | Positive supply input, nominally 5 V. Decouple with a 0.1 µF ceramic capacitor to VSS placed close to the pin. |+| 4 | RXD | output | Receive data output to the CAN protocol controller. Reports the received bus state: logic-low = dominant, logic-high = recessive. CMOS push-pull output referenced to VDD. |+| 5 | SPLIT | output | Common-mode stabilization output for split-termination networks (nominally VDD/2). Tied to the midpoint of two 60 Ω termination resistors (with a small filter capacitor to VSS) to reduce common-mode emissions on the CAN bus. May be left unconnected if a standard single 120 Ω termination is used. |+| 6 | CANL | bidirectional | CAN bus low-side differential I/O. Driven low in the dominant state and biased to VDD/2 in the recessive state. Withstands ±58 V bus faults (ISO 11898-5). |+| 7 | CANH | bidirectional | CAN bus high-side differential I/O. Driven high in the dominant state and biased to VDD/2 in the recessive state. Withstands ±58 V bus faults (ISO 11898-5). |+| 8 | STBY | input | Standby mode control input. Normal Operation when VIL < 0.3 VDD (tie low or drive low); Standby (low-power) mode when VIH > 0.7 VDD (float, pull up, or drive high). Includes an internal worst-case pull-up of ~500 kΩ, so any external pull-down resistor must be < 100 kΩ to guarantee VIL. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## Ordering variants++- `MCP2561T-EE/SN`+- `MCP2561T-ET-E/SN`+- `MCP2561T-EH/SN`+- `MCP2561T-ET-H/SN`+- `MCP2561T-EE/P`+- `MCP2561T-EH/P`+- `MCP2561T-EE/MF`+- `MCP2561T-ET-E/MF`+- `MCP2561T-EH/MF`+- `MCP2561T-ET-H/MF`++## CAD (KiCad official)++- Symbol: `MCP2561T-E`+- 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/mcp2561t-e-datasheet.pdf) (6 pp, sha256 `f65446651abab422`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
