NCV7321D12R2G from onsemi, in a SOIC-8. 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 | RxD | output | Open-drain output for received LIN data, driven low when bus is in dominant state (≤0.4×VBB) with 1.5 mA maximum sink current. |
| 2 | EN | input | Digital enable input with internal pull-down (150-650 kΩ) requiring high level (≥2 V) held for ≥2-18.5 μs to enter normal mode. |
| 3 | WAKE | input | High voltage input for local wake-up detection via falling edge, accepts -35 to +45 V maximum with internal pull-up current source (1-30 μA). |
| 4 | TxD | input | Digital transmit input with switchable pull-down (weak 150-650 kΩ or strong 1.5 mA) and 15-50 ms timeout to release bus if held low. |
| 5 | GND | power_in | Ground reference and supply return for the device. |
| 6 | LIN | bidirectional | Bidirectional LIN bus transceiver interface accepting ±45 V with 40-200 mA short-circuit limiting and internal 30 kΩ termination resistor. |
| 7 | VBB | power_in | Battery supply input accepting 5-27 V nominal (absolute maximum ±45 V) delivering 1.6-30 mA current depending on operating mode. |
| 8 | INH | output | Output driver for external regulator control with 15 mA capability and 0.05-0.75 V drop when active, floating in sleep/unpowered modes. |
