Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1A | bidirectional | Switch 1 analog/digital I/O terminal A. Connects to 1B when control input 1C is high; otherwise high-impedance. Signal range 0 V to VCC. |
| 2 | 1B | bidirectional | Switch 1 analog/digital I/O terminal B. Connects to 1A when control input 1C is high; otherwise high-impedance. |
| 3 | 2B | bidirectional | Switch 2 analog/digital I/O terminal B. Connects to 2A when control input 2C is high; otherwise high-impedance. |
| 4 | 2A | bidirectional | Switch 2 analog/digital I/O terminal A. Connects to 2B when control input 2C is high; otherwise high-impedance. |
| 5 | 2C | input | Switch 2 control input. Active-high digital control that closes the 2A↔2B switch. VIH ≈ 0.7·VCC (4.2 V at VCC=6 V); VIL ≈ 0.2·VCC (1.2 V max at VCC=6 V). Input current ±0.1 µA typ. |
| 6 | 3C | input | Switch 3 control input. Active-high digital control that closes the 3A↔3B switch. VIH ≈ 0.7·VCC; VIL ≈ 0.2·VCC. |
| 7 | GND | power_in | Ground reference (0 V). Sets the lower bound of the analog signal range and control-input logic reference. |
| 8 | 3A | bidirectional | Switch 3 analog/digital I/O terminal A. Connects to 3B when control input 3C is high; otherwise high-impedance. |
| 9 | 3B | bidirectional | Switch 3 analog/digital I/O terminal B. Connects to 3A when control input 3C is high; otherwise high-impedance. |
| 10 | 4B | bidirectional | Switch 4 analog/digital I/O terminal B. Connects to 4A when control input 4C is high; otherwise high-impedance. |
| 11 | 4A | bidirectional | Switch 4 analog/digital I/O terminal A. Connects to 4B when control input 4C is high; otherwise high-impedance. |
| 12 | 4C | input | Switch 4 control input. Active-high digital control that closes the 4A↔4B switch. VIH ≈ 0.7·VCC; VIL ≈ 0.2·VCC. |
| 13 | 1C | input | Switch 1 control input. Active-high digital control that closes the 1A↔1B switch. VIH ≈ 0.7·VCC; VIL ≈ 0.2·VCC. |
| 14 | VCC | power_in | Positive supply voltage. Recommended range 2 V-6 V (nominal 5 V); absolute max 7 V. Sets the upper bound of the analog signal range and control-input logic thresholds. ICC ≤ 20 µA. Bypass with 0.1 µF ceramic to GND close to pin. |
