74LVC4066PW 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 Independent input/output terminal of analog switch 1. Paired with 1Z through the bilateral switch; conducts when 1E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
2 1Z bidirectional Independent output/input terminal of analog switch 1. Paired with 1Y through the bilateral switch; conducts when 1E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
3 2Z bidirectional Independent output/input terminal of analog switch 2. Paired with 2Y through the bilateral switch; conducts when 2E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
4 2Y bidirectional Independent input/output terminal of analog switch 2. Paired with 2Z through the bilateral switch; conducts when 2E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
5 2E input Active-HIGH enable input for switch 2. LOW turns switch 2 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant).
6 3E input Active-HIGH enable input for switch 3. LOW turns switch 3 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant).
7 GND power_in Ground reference (0 V) for the device.
8 3Y bidirectional Independent input/output terminal of analog switch 3. Paired with 3Z through the bilateral switch; conducts when 3E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
9 3Z bidirectional Independent output/input terminal of analog switch 3. Paired with 3Y through the bilateral switch; conducts when 3E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
10 4Z bidirectional Independent output/input terminal of analog switch 4. Paired with 4Y through the bilateral switch; conducts when 4E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
11 4Y bidirectional Independent input/output terminal of analog switch 4. Paired with 4Z through the bilateral switch; conducts when 4E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA.
12 4E input Active-HIGH enable input for switch 4. LOW turns switch 4 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant).
13 1E input Active-HIGH enable input for switch 1. LOW turns switch 1 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant).
14 VCC power_in Supply voltage input. Operating range 1.65 V to 5.5 V; absolute max 6.5 V. Decouple to GND with a local bypass capacitor.
