## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 2Y0 | bidirectional | Analog channel 0 switch terminal of multiplexer 2, connected to 2-COM when INH is low and B and A are both low, with signal voltage 0 to VCC. |
| 2 | 2Y2 | bidirectional | Analog channel 2 switch terminal of multiplexer 2, connected to 2-COM when INH is low, B is high and A is low, with signal voltage 0 to VCC. |
| 3 | 2-COM | bidirectional | Common analog input/output terminal of multiplexer 2, with signal voltage 0 to VCC. |
| 4 | 2Y3 | bidirectional | Analog channel 3 switch terminal of multiplexer 2, connected to 2-COM when INH is low and B and A are both high, with signal voltage 0 to VCC. |
| 5 | 2Y1 | bidirectional | Analog channel 1 switch terminal of multiplexer 2, connected to 2-COM when INH is low, B is low and A is high, with signal voltage 0 to VCC. |
| 6 | INH | input | Inhibit control input that turns all channels off (None on channel) when high; VIL is 0.5 V max at VCC = 2 V and VIH is 1.5 V min at VCC = 2 V. |
| 7 | NC | unconnected | No internal connection. |
| 8 | GND | power_in | Ground pin; continuous current through VCC or GND is limited to ±50 mA. |
| 9 | B | input | Channel select input B (high-order bit) that together with A selects one of four channels in both multiplexers, with input voltage 0 to VCC. |
| 10 | A | input | Channel select input A (low-order bit) that together with B selects one of four channels in both multiplexers, with input voltage 0 to VCC. |
| 11 | 1Y3 | bidirectional | Analog channel 3 switch terminal of multiplexer 1, connected to 1-COM when INH is low and B and A are both high, with signal voltage 0 to VCC. |
| 12 | 1Y0 | bidirectional | Analog channel 0 switch terminal of multiplexer 1, connected to 1-COM when INH is low and B and A are both low, with signal voltage 0 to VCC. |
| 13 | 1-COM | bidirectional | Common analog input/output terminal of multiplexer 1, with signal voltage 0 to VCC. |
| 14 | 1Y1 | bidirectional | Analog channel 1 switch terminal of multiplexer 1, connected to 1-COM when INH is low, B is low and A is high, with signal voltage 0 to VCC. |
| 15 | 1Y2 | bidirectional | Analog channel 2 switch terminal of multiplexer 1, connected to 1-COM when INH is low, B is high and A is low, with signal voltage 0 to VCC. |
| 16 | VCC | power_in | Positive supply voltage, recommended 2 V to 5.5 V and absolute maximum 6 V. |
