TJA1050M from HGSEMI, in a SOP-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 | Transmit data input: a low level drives the bus dominant, the pin has an internal pull-up to VCC so it stays recessive when unused, and the transmitter is disabled if TXD is held low longer than the dominant timeout tdom (300-1000 µs). |
| 2 | GND | power_in | Ground reference for the transceiver. |
| 3 | VCC | power_in | Supply voltage, specified at 4.75-5.25 V for operation, with an absolute maximum of −0.3 to 6 V (no time limit). |
| 4 | RXD | output | Receive data output that reads the bus differential state; in normal mode it is driven high when the bus is recessive, with VOH of VCC−0.4 V at −0.4 mA typical, and it is floating when VCC is lost. |
| 5 | SPLIT | power_out | Common-mode voltage regulator output that holds 0.5 VCC (0.3-0.7 VCC for ±500 µA) in normal mode, is floating in standby mode, and is intended to be connected to the centre tap of a split termination; absolute voltage limit −27 to 40 V. |
| 6 | CANL | bidirectional | Low-level CAN bus line: dominant output 0.5-1.75 V (typ. 1.4 V) with TXD low, short-circuit current 40-100 mA, and the bus pin is rated −27 to 40 V DC. |
| 7 | CANH | bidirectional | High-level CAN bus line: dominant output 3-4.25 V (typ. 3.6 V) with TXD low, short-circuit current −40 to −95 mA, and the bus pin is rated −27 to 40 V DC. |
| 8 | STB | input | Standby mode control input: low selects normal mode and high selects standby; the pin has an internal pull-up to VCC, with VIH of 2 V to VCC+0.3 V and VIL of −0.3 to 0.8 V. |
