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. |
