CD4066DMS

HGSEMI · Analog Switches, Multiplexers · QSOP-16

CD4066DMS from HGSEMI, in a QSOP-16. 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 IN/OUT A bidirectional Switch A analog signal terminal (bidirectional). Paired with pin 2 through the SPST switch; either pin may serve as input or output. Signal range VSS ≤ VIS ≤ VDD.
2 OUT/IN A bidirectional Switch A analog signal terminal (bidirectional). Paired with pin 1 through the SPST switch.
3 OUT/IN B bidirectional Switch B analog signal terminal (bidirectional). Paired with pin 4.
4 IN/OUT B bidirectional Switch B analog signal terminal (bidirectional). Paired with pin 3.
5 EN B input Switch B control (enable) input. Logic 1 (EN=VDD) closes the switch; logic 0 (EN=VSS) opens it (Hi-Z). Very high input impedance CMOS control.
6 EN C input Switch C control (enable) input. Logic 1 closes the switch; logic 0 opens it.
7 VSS power_in Negative supply / ground reference. VDD-VSS operating range 3 V to 15 V (absolute max 18 V). Analog signals must remain between VSS and VDD.
8 NC unconnected No internal connection.
9 NC unconnected No internal connection.
10 IN/OUT C bidirectional Switch C analog signal terminal (bidirectional). Paired with pin 11.
11 OUT/IN C bidirectional Switch C analog signal terminal (bidirectional). Paired with pin 10.
12 OUT/IN D bidirectional Switch D analog signal terminal (bidirectional). Paired with pin 13.
13 IN/OUT D bidirectional Switch D analog signal terminal (bidirectional). Paired with pin 12.
14 EN D input Switch D control (enable) input. Logic 1 closes the switch; logic 0 opens it.
15 EN A input Switch A control (enable) input. Logic 1 closes the switch; logic 0 opens it.
16 VDD power_in Positive supply. VDD-VSS operating range 3 V to 15 V; absolute max 18 V. Also sets logic-high threshold for the EN inputs.

CAD (KiCad official)

  • Symbol: CD4066DMS
  • Footprint: Package_SO:QSOP-16_3.9x4.9mm_P0.635mm
  • 3D model: QSOP-16 (KiCad packages3D, STEP)
  • 3D model files: cd4066dms-etched.step / cd4066dms-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cd4066dms.step / cd4066dms.glb are the bare package body.

Provenance

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

  • Datasheet: HGSEMI datasheet (13 pp, sha256 9ac7644695df6892, 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.
