TCAN1042HVDRQ1 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 | TXD | input | CAN transmit data input from the local protocol controller. LOW drives a dominant bus state, HIGH allows a recessive bus state. Referenced to V_IO logic levels (0.7V_IO High / 0.3V_IO Low). Includes a driver dominant time-out that recovers the bus if TXD is stuck low. |
| 2 | GND | power_in | Ground reference for the transceiver. All voltages in the datasheet are referenced to this terminal. |
| 3 | VCC | power_in | Transceiver 5 V supply voltage. Recommended operating range 4.5 V to 5.5 V. Supplies the CAN bus driver and internal analog circuitry; requires local bypass capacitance. |
| 4 | RXD | output | CAN receive data output to the local protocol controller. LOW indicates a dominant bus state, HIGH indicates a recessive bus state. Output high level is referenced to V_IO on 'V' suffix devices. Drive capability ±2 mA (absolute max ±8 mA). |
| 5 | VIO | power_in | I/O level-shifting supply voltage (3 V to 5.5 V) used to match the logic-side supply of the host MCU. Sets the TXD/STB input thresholds and the RXD output high level. Required only on 'V' suffix devices; supports undervoltage-protected mode (UV_VIO ≈ 1.3-2.75 V). |
| 6 | CANL | bidirectional | Low-side CAN bus I/O line. Differential bus terminal paired with CANH. Fault-protected to ±70 V on the 'H' variants, common-mode input range ±30 V. Tolerates up to ±70 V differential (V_DIFF). |
| 7 | CANH | bidirectional | High-side CAN bus I/O line. Differential bus terminal paired with CANL. Fault-protected to ±70 V on the 'H' variants, common-mode input range ±30 V. |
| 8 | STB | input | Standby mode control input (active high). Drive LOW for normal operation; drive HIGH to enter low-power standby with remote wake-up (WUP) monitoring. Referenced to V_IO logic levels on 'V' suffix devices. |
