TCAN1044VDDFRQ1 from Texas Instruments, in a TSOT-23-8. 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 | TXD | input | CAN transmit data input with logic levels 0.7×VIO (high) and 0.3×VIO (low) |
| 2 | GND | power_in | Ground connection |
| 3 | VCC | power_in | 5V power supply input with operating range 4.5V to 5.5V |
| 4 | RXD | output | CAN receive data output with logic levels 0.8×VIO (high) and 0.2×VIO (low), tri-state when powered off |
| 5 | VIO | power_in | I/O supply voltage 1.7V to 5.5V for digital logic level shifting supporting 1.8V, 2.5V, 3.3V, and 5V applications |
| 6 | CANL | bidirectional | Low-level CAN bus line with ±58V bus fault protection, ±12V common mode input range, and 40kΩ to 90kΩ differential input resistance |
| 7 | CANH | bidirectional | High-level CAN bus line with ±58V bus fault protection, ±12V common mode input range, and 40kΩ to 90kΩ differential input resistance |
| 8 | STB | input | Standby mode input with integrated pull-up (high for low-power standby mode, low for normal operating mode) |
