Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | Y4 | bidirectional | Independent input/output channel Y4, connected to Z when E is LOW and S2=H, S1=L, S0=L. |
| 2 | Y6 | bidirectional | Independent input/output channel Y6, connected to Z when E is LOW and S2=H, S1=H, S0=L. |
| 3 | Z | bidirectional | Common input/output that connects to the selected Yn channel while E is LOW; switches are off when E is HIGH. |
| 4 | Y7 | bidirectional | Independent input/output channel Y7, connected to Z when E is LOW and S2=H, S1=H, S0=H. |
| 5 | Y5 | bidirectional | Independent input/output channel Y5, connected to Z when E is LOW and S2=H, S1=L, S0=H. |
| 6 | E | input | Enable input (active LOW); when HIGH, all switches are turned off. |
| 7 | VEE | power_in | Supply voltage pin VEE for the analog switch section, as listed in the pin description table. |
| 8 | GND | power_in | Ground supply voltage; the limiting values are referenced to VSS = 0 V (ground). |
