**Texas Instruments** · LIN Transceivers · SOIC-8-EP

TLIN10285DDARQ1 from Texas Instruments, in a SOIC-8-EP. 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 | VSUP | power_in | Device supply voltage (connected to battery in series with external reverse-blocking diode). |
| 2 | EN | input | Enable input. |
| 3 | GND | power_in | Ground. |
| 4 | LIN | bidirectional | LIN bus single-wire transmitter and receiver. |
| 5 | RXD | tri_state | RXD output (open-drain) interface reporting state of LIN bus voltage. |
| 6 | TXD | input | TXD input interface to control state of LIN output. |
| 7 | nRST | tri_state | Reset output (active low). |
| 8 | VCC | power_out | Output voltage from integrated LDO. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
