SN65LBC031DG4 from Texas Instruments, in a SOIC-8. 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 | TX | input | Transmitter input: VIH is 2 V minimum up to VCC and VIL is 0.8 V maximum, and an internal pullup ensures a defined output during power-up and protocol controller reset. |
| 2 | GND | power_in | Ground terminal; all voltages except the differential bus voltage are measured with respect to GND. |
| 3 | VCC | power_in | Logic supply voltage, 4.5 V minimum to 5.5 V maximum (5 V nominal), with an absolute maximum of 7 V. |
| 4 | RX | output | Receiver output: VOH is at least VCC − 0.5 V at IOH = −400 µA and VOL is at most 0.5 V at IOL = 1 mA. |
| 5 | REF | power_out | Reference output at 0.45 VCC to 0.55 VCC (IREF = ±20 µA) with an output resistance of 5 to 10 kΩ. |
| 6 | CANL | bidirectional | Low-side bus output driver; bus terminal voltage is rated from −5 V to 20 V and the short-circuit output current is 140 to 250 mA. |
| 7 | CANH | bidirectional | High-side bus output driver; bus terminal voltage is rated from −5 V to 20 V and the short-circuit output current is −95 to −200 mA. |
| 8 | ASC | input | Adjustable slope control: leave open or tie to GND for 500 kBaud operation, or tie to VCC to increase bus transition times for 125 kBaud operation. |
