LSF0102DCTR from Texas Instruments, in a MSOP-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 | GND | power_in | Ground reference for the device. |
| 2 | Vref_A | power_in | Reference supply voltage for the A-side (lower-voltage) I/O rail. Recommended range 0-5 V; sets the pass-transistor gate bias together with Vref_B and EN. |
| 3 | A1 | bidirectional | Channel-1 A-side data port. Bidirectional pass-transistor I/O referenced to Vref_A; pairs with B1 to form a level-translated bidirectional link. On-resistance typically 8-30 Ω depending on rail selection. |
| 4 | A2 | bidirectional | Channel-2 A-side data port. Bidirectional pass-transistor I/O referenced to Vref_A; pairs with B2. |
| 5 | B2 | bidirectional | Channel-2 B-side data port. Bidirectional pass-transistor I/O referenced to Vref_B; pairs with A2. |
| 6 | B1 | bidirectional | Channel-1 B-side data port. Bidirectional pass-transistor I/O referenced to Vref_B; pairs with A1. |
| 7 | Vref_B | power_in | Reference supply voltage for the B-side (higher-voltage) I/O rail. Recommended range 0-5 V; must be ≥ Vref_A for down-translation operation. |
| 8 | EN | input | Switch enable input. Connect to Vref_B through a pull-up resistor (typ. 200 kΩ). Drive low to isolate A and B ports (high-Z); drive high (to Vref_B) to enable level translation. |
