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 | RXD | output | RXD is an open-drain output reporting the LIN bus state (high for recessive, low for dominant) and goes low on a wake-up request, requiring an external pull-up if the MCU pin has none. |+| 2 | EN | input | Enable input selecting Normal mode when high and low-power (sleep) mode when low, with an internal pull-down that keeps the device in low-power mode if the pin floats. |+| 3 | NWake | input | High-voltage wake-up input with DC and transient input voltage of -1 V to 40 V through a 33-kΩ series resistor, where a low longer than tNWAKE causes a local wake-up, and an internal pull-up to VSUP. |+| 4 | TXD | input | Transmit input controlling the LIN output, where low drives LIN dominant and high drives it recessive; it is compatible with 3.3 V and 5.0 V I/O, has an internal pull-down, and is protected by the dominant state timeout. |+| 5 | GND | power_in | Device ground connection; the device operates with a ground shift as long as VSUP does not fall below its minimum operating voltage. |+| 6 | LIN | bidirectional | Single-wire LIN bus transmitter and receiver that accepts DC voltages from -40 V to 40 V, with an internal 30-kΩ pull-up and series diode to VSUP for responder applications. |+| 7 | VSUP | power_in | Device supply pin, rated for 7 V to 27 V recommended operation (27 V continuous and 40 V transient absolute maximum), connected to the battery through an external reverse-blocking diode. |+| 8 | INH | output | Inhibit output that drives an external voltage regulator's inhibit input, with the high-side switch on in Normal mode and off in Low Power mode, and output current limited to 2 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Interface |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `TPIC1021DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `tpic1021dr-etched.step` / `tpic1021dr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tpic1021dr.step` / `tpic1021dr.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tpic1021.pdf) (25 pp, sha256 `9ce91d0367264a72`, retrieved 2026-10-08, tier: manufacturer)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
