LSF0102DCTR

Texas Instruments · Translators / Level Shifters · MSOP-8

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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (40 pp, sha256 c3a0e6851ee52e5d, retrieved 2026-08-17, tier: manufacturer)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
