74HC4066PW

Nexperia · Analog Switches, Multiplexers · TSSOP-14

74HC4066PW from Nexperia, in a TSSOP-14. 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 1Y bidirectional Switch 1 independent input/output terminal Y. Bidirectional analog switch pin; paired with 1Z when 1E is HIGH. V_SW range GND to V_CC, switch current up to ±25 mA.
2 1Z bidirectional Switch 1 independent input/output terminal Z. Bidirectional analog switch pin; paired with 1Y when 1E is HIGH.
3 2Z bidirectional Switch 2 independent input/output terminal Z. Bidirectional analog switch pin; paired with 2Y when 2E is HIGH.
4 2Y bidirectional Switch 2 independent input/output terminal Y. Bidirectional analog switch pin; paired with 2Z when 2E is HIGH.
5 2E input Enable input for switch 2 (active HIGH). HIGH closes the 2Y-2Z switch; LOW opens it. CMOS input levels for 74HC4066.
6 3E input Enable input for switch 3 (active HIGH). HIGH closes the 3Y-3Z switch; LOW opens it.
7 GND power_in Ground reference (0 V). Ground current up to -50 mA absolute maximum.
8 3Y bidirectional Switch 3 independent input/output terminal Y. Bidirectional analog switch pin; paired with 3Z when 3E is HIGH.
9 3Z bidirectional Switch 3 independent input/output terminal Z. Bidirectional analog switch pin; paired with 3Y when 3E is HIGH.
10 4Z bidirectional Switch 4 independent input/output terminal Z. Bidirectional analog switch pin; paired with 4Y when 4E is HIGH.
11 4Y bidirectional Switch 4 independent input/output terminal Y. Bidirectional analog switch pin; paired with 4Z when 4E is HIGH.
12 4E input Enable input for switch 4 (active HIGH). HIGH closes the 4Y-4Z switch; LOW opens it.
13 1E input Enable input for switch 1 (active HIGH). HIGH closes the 1Y-1Z switch; LOW opens it.
14 VCC power_in Positive supply voltage. Recommended V_CC = 2.0 to 10.0 V for 74HC4066; absolute maximum -0.5 to +11.0 V. Supply current up to 50 mA absolute maximum.

CAD (KiCad official)

  • Symbol: 74HC4066PW
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: 74hc4066pw-etched.step / 74hc4066pw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 74hc4066pw.step / 74hc4066pw.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
74hc4066pw.step 194 KB You want the bare part, or you mark your own boards.
74hc4066pw-etched.step 2.3 MB You want the part with 74HC4066PW already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 584 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: Nexperia datasheet (21 pp, sha256 3fca0cb9e46e306f, retrieved 2026-08-17, tier: manufacturer)
  • 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).
