## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1Y | bidirectional | Switch 1 analog I/O terminal Y. Bidirectional analog signal path; connects to 1Z through the switch when 1E is HIGH. Input voltage range 0 V to VDD (VDD = 3-9 V). |
| 2 | 1Z | bidirectional | Switch 1 analog I/O terminal Z. Bidirectional analog signal path; connects to 1Y through the switch when 1E is HIGH. Typical RON ~80 Ω at VDD=9 V. |
| 3 | 2Z | bidirectional | Switch 2 analog I/O terminal Z. Bidirectional analog signal path; connects to 2Y through the switch when 2E is HIGH. |
| 4 | 2Y | bidirectional | Switch 2 analog I/O terminal Y. Bidirectional analog signal path; connects to 2Z through the switch when 2E is HIGH. |
| 5 | 2E | input | Switch 2 enable input, active HIGH. HIGH turns switch 2 ON (2Y-2Z conducts); LOW turns it OFF. VIH ≥ 3.5 V at VDD=5 V, ≥ 7 V at VDD=9 V. |
| 6 | 3E | input | Switch 3 enable input, active HIGH. HIGH turns switch 3 ON (3Y-3Z conducts); LOW turns it OFF. |
| 7 | VSS | power_in | Ground (0 V) reference for the device. Analog input voltage range is referenced from VSS to VDD. |
| 8 | 3Y | bidirectional | Switch 3 analog I/O terminal Y. Bidirectional analog signal path; connects to 3Z through the switch when 3E is HIGH. |
| 9 | 3Z | bidirectional | Switch 3 analog I/O terminal Z. Bidirectional analog signal path; connects to 3Y through the switch when 3E is HIGH. |
| 10 | 4Z | bidirectional | Switch 4 analog I/O terminal Z. Bidirectional analog signal path; connects to 4Y through the switch when 4E is HIGH. |
| 11 | 4Y | bidirectional | Switch 4 analog I/O terminal Y. Bidirectional analog signal path; connects to 4Z through the switch when 4E is HIGH. |
| 12 | 4E | input | Switch 4 enable input, active HIGH. HIGH turns switch 4 ON (4Y-4Z conducts); LOW turns it OFF. |
| 13 | 1E | input | Switch 1 enable input, active HIGH. HIGH turns switch 1 ON (1Y-1Z conducts); LOW turns it OFF. |
| 14 | VDD | power_in | Positive supply voltage. Recommended operating range 3 V to 9 V (absolute max +12 V referenced to VSS). Sets the upper analog input range and the logic threshold for the nE control inputs. |
