SN74LV4066ADR from Texas Instruments, 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 | 1A | bidirectional | Input/Output terminal A of analog switch channel 1. Signal passes between 1A and 1B when control input 1C is high. Signal amplitude up to 5.5 V (peak). |
| 2 | 1B | bidirectional | Input/Output terminal B of analog switch channel 1. Bilateral pair with 1A; on-resistance typ 29 Ω at VCC=3 V (150 Ω max). |
| 3 | 2B | bidirectional | Input/Output terminal B of analog switch channel 2. Connects to 2A when 2C is high. |
| 4 | 2A | bidirectional | Input/Output terminal A of analog switch channel 2. Bilateral pair with 2B. |
| 5 | 2C | input | Control input for channel 2. Switch is ON when this pin is at logic high; OFF when low. Logic input voltage range 0-5.5 V; VIH = VCC×0.7 typical. |
| 6 | 3C | input | Control input for channel 3. Switch is ON when this pin is at logic high; OFF when low. |
| 7 | GND | power_in | Ground (0 V) reference for the device. |
| 8 | 3A | bidirectional | Input/Output terminal A of analog switch channel 3. Connects to 3B when 3C is high. |
| 9 | 3B | bidirectional | Input/Output terminal B of analog switch channel 3. Bilateral pair with 3A. |
| 10 | 4B | bidirectional | Input/Output terminal B of analog switch channel 4. Connects to 4A when 4C is high. |
| 11 | 4A | bidirectional | Input/Output terminal A of analog switch channel 4. Bilateral pair with 4B. |
| 12 | 4C | input | Control input for channel 4. Switch is ON when this pin is at logic high; OFF when low. |
| 13 | 1C | input | Control input for channel 1. Switch is ON when this pin is at logic high; OFF when low. |
| 14 | VCC | power_in | Positive supply, 1.65 V to 5.5 V (7 V absolute max). Bypass to GND with a 0.1 µF to 10 µF decoupling capacitor for reliable operation. |
