74HCT4066D from Nexperia, in a SOIC-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 analog input/output terminal (nY). Connected through switch 1 to 1Z when 1E is HIGH.
2 1Z bidirectional Switch 1 independent analog input/output terminal (nZ). Connected through switch 1 to 1Y when 1E is HIGH.
3 2Z bidirectional Switch 2 independent analog input/output terminal (nZ). Connected through switch 2 to 2Y when 2E is HIGH.
4 2Y bidirectional Switch 2 independent analog input/output terminal (nY). Connected through switch 2 to 2Z when 2E is HIGH.
5 2E input Switch 2 enable input (active HIGH). HIGH turns switch 2 ON; LOW turns it OFF. TTL-compatible thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V at VCC=4.5-5.5 V).
6 3E input Switch 3 enable input (active HIGH). HIGH turns switch 3 ON; LOW turns it OFF. TTL-compatible thresholds.
7 GND power_in Ground reference (0 V). All signals are referenced to GND.
8 3Y bidirectional Switch 3 independent analog input/output terminal (nY). Connected through switch 3 to 3Z when 3E is HIGH.
9 3Z bidirectional Switch 3 independent analog input/output terminal (nZ). Connected through switch 3 to 3Y when 3E is HIGH.
10 4Z bidirectional Switch 4 independent analog input/output terminal (nZ). Connected through switch 4 to 4Y when 4E is HIGH.
11 4Y bidirectional Switch 4 independent analog input/output terminal (nY). Connected through switch 4 to 4Z when 4E is HIGH.
12 4E input Switch 4 enable input (active HIGH). HIGH turns switch 4 ON; LOW turns it OFF. TTL-compatible thresholds.
13 1E input Switch 1 enable input (active HIGH). HIGH turns switch 1 ON; LOW turns it OFF. TTL-compatible thresholds.
14 VCC power_in Positive supply voltage. Recommended operating range for 74HCT4066: 4.5 V to 5.5 V (absolute max 11 V). Bypass with a local decoupling capacitor to GND.
