GR · Analog Switches, Multiplexers · SC-70-5

74LVC1G66CT05ARCQ from GR, in a SC-70-5. 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 A bidirectional Bidirectional analog switch I/O terminal A. Connects to switch terminal B when control input C is high. Signal voltage range 0 V to VCC (up to 5.5 V peak).
2 B bidirectional Bidirectional analog switch I/O terminal B. Connects to switch terminal A when control input C is high. Signal voltage range 0 V to VCC (up to 5.5 V peak).
3 GND power_in Ground reference (0 V).
4 C input Digital control input for the analog switch. Low = switch OFF (A disconnected from B); High = switch ON. VIH = VCC × 0.65-0.7 depending on VCC range; VIL = VCC × 0.3-0.35.
5 VCC power_in Positive supply voltage input, 1.65 V to 5.5 V operating range (absolute max 6.5 V). Bypass with a local decoupling capacitor to GND.

Provenance

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

  • Datasheet: GR datasheet (12 pp, sha256 fca52bfef5407645, retrieved 2026-08-17, tier: lcsc)
  • 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).
