## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | B1 | bidirectional | B channel Y in/out switch connection. |
| 2 | B0 | bidirectional | B channel X in/out switch connection. |
| 3 | C1 | bidirectional | C channel Y in/out switch connection. |
| 4 | COM C | bidirectional | C common out/in; selected C channel connects here. |
| 5 | C0 | bidirectional | C channel X in/out switch connection. |
| 6 | !E | input | Enable channels (Active Low); when high, disables all switches to OFF state. |
| 7 | VEE | power_in | Negative power supply input; range 0 to -6 V. |
| 8 | GND | power_in | Ground reference. |
| 9 | S2 | input | Channel select input 2 (binary address MSB); VIH = 2 V min, VIL = 0.8 V max. |
| 10 | S1 | input | Channel select input 1 (binary address); VIH = 2 V min, VIL = 0.8 V max. |
| 11 | S0 | input | Channel select input 0 (binary address LSB); VIH = 2 V min, VIL = 0.8 V max. |
| 12 | A0 | bidirectional | A channel X in/out switch connection. |
| 13 | A1 | bidirectional | A channel Y in/out switch connection. |
| 14 | COM A | bidirectional | A common out/in; selected A channel connects here. |
| 15 | COM B | bidirectional | B common out/in; selected B channel connects here. |
| 16 | VCC | power_in | Positive power supply input; range 4.5 to 5.5 V for HCT type. |
