GS3221-CR

Gainsil · Analog Switches / Multiplexers · SC-70-6

GS3221-CR from Gainsil, 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 NO passive Normally-Open analog switch terminal. Bidirectional analog signal path connected to COM when IN is high. Signal range is VSS to VDD; on-resistance is 1.5Ω typ. with ICOM = -10 mA.
2 VSS power_in Negative supply / ground reference for the analog switch. Typically tied to GND for single-supply operation. VDD-VSS supply range 1.8V to 5.5V (absolute max 7.5V).
3 NC passive Normally-Closed analog switch terminal. Bidirectional analog signal path connected to COM when IN is low. Signal range is VSS to VDD; on-resistance is 1.5Ω typ.
4 COM passive Common analog switch terminal (the SPDT pole). Routed to NO when IN=high and to NC when IN=low, with a break-before-make transition (~23 ns TBBM at VS=5V).
5 VDD power_in Positive supply input, +1.8V to +5.5V (absolute max +7.5V vs VSS). Bypass with a 0.1 µF ceramic capacitor to VSS. Supply current is 1 µA max.
6 IN input Digital control input selecting the switch path (high → COM-NO, low → COM-NC). TTL/CMOS compatible: VIH ≥ 1.5V at VS=5V (0.9V at VS=3V); VIL ≤ 0.55V at VS=5V. Tolerates drive up to 5.5V independent of VDD; input leakage ±1 µA max.

  • Footprint: Package_TO_SOT_SMD:SOT-363_SC-70-6
  • 3D model: SC-70-6 (KiCad packages3D, STEP)
  • 3D model files: gs3221-cr-etched.step / gs3221-cr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs3221-cr.step / gs3221-cr.glb are the bare package body.

Provenance

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

  • Datasheet: Gainsil datasheet (9 pp, sha256 4287cb24d7821606, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
