TCAN1042HDRQ1 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. LOW drives the bus dominant, HIGH lets the bus recess. Logic input range -0.3 V to 7 V (or VIO+0.3 V on 'V' devices). |
| 2 | GND | power_in | Ground connection (0 V reference). For DRB (VSON) package options the thermal pad may be connected to GND to optimize thermal characteristics. |
| 3 | VCC | power_in | Transceiver 5-V supply voltage. Recommended operating range 4.5 V to 5.5 V; absolute maximum -0.3 V to 7 V. |
| 4 | RXD | output | CAN receive data output. LOW when bus is dominant, HIGH when bus is recessive. Output drive ±2 mA (recommended), ±8 mA (absolute max). On non-'V' devices, driven to VCC logic levels. |
| 5 | NC | unconnected | No connect. On base/H/G/HG suffix devices this pin is unused (leave floating or tie appropriately). On 'V' suffix parts this pin is used as VIO instead. |
| 6 | CANL | bidirectional | Low-level CAN differential bus I/O line. Bus fault protection ±70 V (H suffix); differential absolute maximum ±70 V (H). Includes ±15 kV IEC ESD protection. |
| 7 | CANH | bidirectional | High-level CAN differential bus I/O line. Bus fault protection ±70 V (H suffix); differential absolute maximum ±70 V (H). Includes ±15 kV IEC ESD protection. |
| 8 | STB | input | Standby mode control input, active HIGH. Drive HIGH to place the transceiver in Low Power Standby Mode with Remote Wake capability; LOW selects normal operation. |
