LSF0102QDCURQ1 from Texas Instruments, in a VSSOP-8-0.5mm. 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 connection; must be connected to system ground. |
| 2 | Vref_A | power_in | A side reference supply voltage for voltage translation level; operating range 0.95 V to 5.5 V. |
| 3 | A1 | bidirectional | Input/Output A port for Channel 1; bidirectional signal pin that operates as part of voltage translation between A and B sides. |
| 4 | A2 | bidirectional | Input/Output A port for Channel 2; bidirectional signal pin that operates as part of voltage translation between A and B sides. |
| 5 | B2 | bidirectional | Input/Output B port for Channel 2; bidirectional signal pin that operates as part of voltage translation between B and A sides. |
| 6 | B1 | bidirectional | Input/Output B port for Channel 1; bidirectional signal pin that operates as part of voltage translation between B and A sides. |
| 7 | Vref_B | power_in | B side reference supply voltage; must be connected to supply through 200 kΩ resistor; operating range Vref_A + 0.8 V to 5.5 V. |
| 8 | EN | input | I/O enable input; tie directly to Vref_B to enable all I/O pins, pull LOW to disable all I/O pins and place them in high impedance state. |
