SN74LV4066ADBR from Texas Instruments, in a SSOP-14-208mil. 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 | Switch channel 1 analog/digital I/O terminal A. Connects to 1B when the 1C control is high; supports signal swing 0 V to VCC with rON typ 21 Ω at VCC=4.5 V. |
| 2 | 1B | bidirectional | Switch channel 1 analog/digital I/O terminal B. Connects to 1A when the 1C control is high. |
| 3 | 2B | bidirectional | Switch channel 2 analog/digital I/O terminal B. Connects to 2A when the 2C control is high. |
| 4 | 2A | bidirectional | Switch channel 2 analog/digital I/O terminal A. Connects to 2B when the 2C control is high. |
| 5 | 2C | input | Control line for channel 2. Switch is ON (2A↔2B closed) when this pin is at a logic high (VIH ≥ VCC × 0.7); a logic low opens the switch. |
| 6 | 3C | input | Control line for channel 3. Switch is ON (3A↔3B closed) when this pin is high; opens when low. |
| 7 | GND | power_in | Ground (0 V) reference for the device. |
| 8 | 3A | bidirectional | Switch channel 3 analog/digital I/O terminal A. Connects to 3B when the 3C control is high. |
| 9 | 3B | bidirectional | Switch channel 3 analog/digital I/O terminal B. Connects to 3A when the 3C control is high. |
| 10 | 4B | bidirectional | Switch channel 4 analog/digital I/O terminal B. Connects to 4A when the 4C control is high. |
| 11 | 4A | bidirectional | Switch channel 4 analog/digital I/O terminal A. Connects to 4B when the 4C control is high. |
| 12 | 4C | input | Control line for channel 4. Switch is ON (4A↔4B closed) when this pin is high; opens when low. |
| 13 | 1C | input | Control line for channel 1. Switch is ON (1A↔1B closed) when this pin is high; opens when low. |
| 14 | VCC | power_in | Positive power supply, 1.65 V to 5.5 V. This is the most positive supply potential and also sets the maximum switch signal range. Bypass with 0.1 µF to 10 µF between VCC and GND. |
