ISO1044BD 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 | VCC1 | power_in | Digital-side supply voltage, Side 1, supporting 1.71 V to 5.5 V operating range. |
| 2 | TXD | input | CAN transmit data input with LOW for dominant and HIGH for recessive bus states. |
| 3 | RXD | output | CAN receive data output with LOW for dominant and HIGH for recessive bus states. |
| 4 | GND1 | power_in | Digital-side ground connection, Side 1. |
| 5 | CANL | bidirectional | Low-level CAN bus line with absolute maximum voltage rating -58 V to 58 V. |
| 6 | CANH | bidirectional | High-level CAN bus line with absolute maximum voltage rating -58 V to 58 V. |
| 7 | GND2 | power_in | Transceiver-side ground connection, Side 2. |
| 8 | VCC2 | power_in | Transceiver-side supply voltage, Side 2, supporting 4.5 V to 5.5 V operating range. |
