Texas Instruments · Analog Switches, Multiplexers · SC-70-6

1P1G3157QDCKRQ1 from Texas Instruments, in a SC-70-6. 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 B2 bidirectional Analog switch throw terminal 2 (second common terminal). Bidirectional analog/digital I/O; connected to A when S is high. Signal range 0 to VCC.
2 GND power_in Ground reference (0 V).
3 B1 bidirectional Analog switch throw terminal 1 (first common terminal). Bidirectional analog/digital I/O; connected to A when S is low. Signal range 0 to VCC.
4 A bidirectional Analog switch pole (common terminal). Bidirectional I/O routed to either B1 or B2 depending on the S select input. Signal range 0 to VCC.
5 VCC power_in Positive supply voltage. Recommended operating range 1.65 V to 5.5 V; absolute maximum 6.5 V.
6 S input Digital select input. Low routes A to B1; high routes A to B2. VIH ≈ 0.7×VCC, VIL ≈ 0.3×VCC at VCC ≥ 2.3 V.

Provenance

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

  • Datasheet: Texas Instruments datasheet (29 pp, sha256 09bbd4ffa0be4a5a, retrieved 2026-08-17, tier: lcsc)
  • 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).
