TCAN1043HDQ1 from Texas Instruments, in a SOIC-14. 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, low for dominant and high for recessive bus states. |
| 2 | GND | power_in | Ground connection. |
| 3 | VCC | power_in | 5 V CAN bus supply voltage; the absolute maximum rating is -0.3 V to 7 V (page 5). |
| 4 | RXD | tri_state | CAN receive data output, low for dominant and high for recessive bus states, with tri-state capability. |
| 5 | VIO | power_in | I/O supply voltage for logic level shifting, rated -0.3 V to 7 V absolute maximum (page 5) and 2.8 V to 5.5 V in the features list (page 1). |
| 6 | EN | input | Enable input for mode control, with an integrated pull-down. |
| 7 | INH | output | High-voltage output that can be used to control system voltage regulators; absolute maximum INH pin voltage for H versions is -0.3 V to 70 V (page 5). |
| 8 | nFAULT | output | Fault output with inverted logic; logic output current is limited to 8 mA absolute maximum (page 5). |
| 9 | WAKE | input | High-voltage wake input terminal; for H versions the WAKE pin voltage range is -0.3 V to 70 V (page 5). |
| 10 | VSUP | power_in | Reverse-blocked battery supply input; absolute maximum battery supply voltage is 70 V for H versions (page 5). |
| 11 | NC | unconnected | No connect, not internally connected. |
| 12 | CANL | bidirectional | Low-level CAN bus input/output line; the CAN bus I/O voltage range for H versions is -70 V to 70 V (page 5). |
| 13 | CANH | bidirectional | High-level CAN bus input/output line; the CAN bus I/O voltage range for H versions is -70 V to 70 V (page 5). |
| 14 | nSTB | input | Standby input for mode control, with an integrated pull-down. |
