## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 2Y1 | bidirectional | Input to analog multiplexer 2, bidirectional signal port accepting signals from 0 to VCC volts. |
| 2 | 2Y0 | bidirectional | Input to analog multiplexer 2, bidirectional signal port accepting signals from 0 to VCC volts. |
| 3 | 3Y1 | bidirectional | Input to analog multiplexer 3, bidirectional signal port accepting signals from 0 to VCC volts. |
| 4 | 3-COM | bidirectional | Multiplexer 3 common terminal, output in multiplexer mode or input in demultiplexer mode. |
| 5 | 3Y0 | bidirectional | Input to analog multiplexer 3, bidirectional signal port accepting signals from 0 to VCC volts. |

| 9 | C | input | Selector line for channel selection, binary address input used with B and A to select active channels. |
| 10 | B | input | Selector line for channel selection, binary address input used with C and A to select active channels. |
| 11 | A | input | Selector line for channel selection, binary address input used with C and B to select active channels. |
| 12 | 1Y0 | bidirectional | Input to analog multiplexer 1, bidirectional signal port accepting signals from 0 to VCC volts. |
| 13 | 1Y1 | bidirectional | Input to analog multiplexer 1, bidirectional signal port accepting signals from 0 to VCC volts. |
| 14 | 1-COM | bidirectional | Multiplexer 1 common terminal, output in multiplexer mode or input in demultiplexer mode. |
| 15 | 2-COM | bidirectional | Multiplexer 2 common terminal, output in multiplexer mode or input in demultiplexer mode. |
| 16 | VCC | power_in | Positive power supply input, 1.65V to 5.5V operating range. |
