JSM1040T from JSMSEMI, 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; TXD high drives the CAN bus recessive, TXD low drives the bus dominant (abs max -0.3 V to Vcc+0.3 V). |
| 2 | GND | power_in | Ground reference. |
| 3 | VCC | power_in | Supply voltage input, recommended 4.5 V to 5.5 V (5 V typ), absolute maximum +6 V. |
| 4 | RXD | output | Receiver data output; high when the CAN bus is recessive and low when the bus is dominant. |
| 5 | SPLIT | output | Common-mode stabilization output, abs max -50 V to +50 V. |
| 6 | CANL | bidirectional | Low-level CAN bus line, abs max -58 V to +58 V, recommended bus input -12 V to 12 V. |
| 7 | CANH | bidirectional | High-level CAN bus line, abs max -58 V to +58 V, recommended bus input -12 V to 12 V. |
| 8 | STB | input | Standby mode control input; low selects high-speed mode, high selects low-power bus-monitoring standby mode (abs max -0.3 V to Vcc+0.3 V). |
