LSF0102DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 | GND | power_in | Ground reference pin for the device. |
| 2 | Vref_A | power_in | A-side reference supply voltage; it must be 0.9 V minimum and is the lowest voltage level for all inputs and outputs (recommended range 0.9 V to 5.5 V). |
| 3 | A1 | bidirectional | Auto-bidirectional data port A1 on the low-voltage side, with recommended input/output voltage of 0 V to 5.5 V. |
| 4 | A2 | bidirectional | Auto-bidirectional data port A2 on the low-voltage side, with recommended input/output voltage of 0 V to 5.5 V. |
| 5 | B2 | bidirectional | Auto-bidirectional data port B2 on the high-voltage side, with recommended input/output voltage of 0 V to 5.5 V. |
| 6 | B1 | bidirectional | Auto-bidirectional data port B1 on the high-voltage side, with recommended input/output voltage of 0 V to 5.5 V. |
| 7 | Vref_B | power_in | B-side reference supply voltage; it must be at least Vref_A + 0.8 V and at most 5.5 V, and it is connected to EN through a 200 kΩ bias resistor. |
| 8 | EN | input | Enable input that must be connected directly to Vref_B and pulled up through a high-value (200 kΩ) bias resistor; driving it low places all I/O pins in high-impedance state. |
