SL1040S from Slkor SLKORMICRO Elec, in a SOP-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 | Transmit data input from the CAN protocol controller. Drives the bus dominant when LOW. Internally pulled up to VCC to force recessive state if left unsupplied. Compatible with 3.3 V and 5 V logic (VIH ≥ 2 V, VIL ≤ 0.8 V). |
| 2 | GND | power_in | Ground supply reference for the device. All voltages are defined with respect to this pin. |
| 3 | VCC | power_in | Supply voltage input, operating range 4.75 V to 5.25 V. ICC is typically 5 mA (recessive) / 50 mA (dominant) in normal mode and ~10 µA in standby mode. |
| 4 | RXD | output | Receive data output; reads out data from the CAN bus lines. LOW = bus dominant / wake-up request detected in standby; HIGH = bus recessive. Floats when VCC is lost to prevent reverse supply. |
| 5 | SPLIT | output | Common-mode stabilization output providing a DC-stabilized 0.5·VCC in normal mode for connection to the center tap of a split bus termination. Floating in standby mode. Short-circuit proof to battery and ground; withstands -27 V to +40 V. |
| 6 | CANL | bidirectional | LOW-level CAN bus line. Typical dominant output 1.4 V (0.5-1.75 V), recessive ~0.5·VCC. Short-circuit protected to battery/ground, withstands -27 V to +40 V, and protected against ISO 7637 automotive transients (±200 V). |
| 7 | CANH | bidirectional | HIGH-level CAN bus line. Typical dominant output 3.6 V (3.0-4.25 V), recessive ~0.5·VCC. Short-circuit protected to battery/ground, withstands -27 V to +40 V, and protected against ISO 7637 automotive transients (±200 V). |
| 8 | STB | input | Standby mode control input. LOW = normal mode (transmit/receive active); HIGH = standby mode (low-power receiver, wake-up capability). Internally pulled up to VCC to default to standby if unsupplied. Compatible with 3.3 V and 5 V logic. |
