ISO1044BDR from Texas Instruments, 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 | VCC1 | power_in | Digital-side supply voltage (Side 1). Operating range 1.71 V to 5.5 V; supports 1.8 V, 2.5 V, 3.3 V, and 5.0 V logic interfaces to the CAN controller. |
| 2 | TXD | input | CAN transmit data input from the MCU. LOW drives a dominant bus state; HIGH allows a recessive bus state. Referenced to VCC1/GND1 domain. |
| 3 | RXD | output | CAN receive data output to the MCU. LOW indicates a dominant bus state; HIGH indicates a recessive bus state. Push-pull output referenced to VCC1/GND1. |
| 4 | GND1 | power_in | Digital-side ground connection (Side 1). Reference for VCC1, TXD, and RXD signals. |
| 5 | CANL | bidirectional | Low-level CAN bus line. Differential bus I/O with the CANH pin; withstands ±58 V bus fault voltage and ±12 V common-mode range. |
| 6 | CANH | bidirectional | High-level CAN bus line. Differential bus I/O with the CANL pin; withstands ±58 V bus fault voltage and ±12 V common-mode range. |
| 7 | GND2 | power_in | Transceiver-side ground connection (Side 2). Reference for VCC2, CANH, and CANL on the isolated bus side. |
| 8 | VCC2 | power_in | Transceiver-side supply voltage (Side 2). Operating range 4.5 V to 5.5 V; powers the CAN bus driver stage. |
