Paired with 1Z through the bilateral switch; conducts when 1E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 2 | 1Z | bidirectional | Independent output/input terminal of analog switch 1. Paired with 1Y through the bilateral switch; conducts when 1E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 3 | 2Z | bidirectional | Independent output/input terminal of analog switch 2. Paired with 2Y through the bilateral switch; conducts when 2E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 4 | 2Y | bidirectional | Independent input/output terminal of analog switch 2. Paired with 2Z through the bilateral switch; conducts when 2E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 5 | 2E | input | Active-HIGH enable input for switch 2. LOW turns switch 2 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant). |+| 6 | 3E | input | Active-HIGH enable input for switch 3. LOW turns switch 3 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant). |+| 7 | GND | power_in | Ground reference (0 V) for the device. |+| 8 | 3Y | bidirectional | Independent input/output terminal of analog switch 3. Paired with 3Z through the bilateral switch; conducts when 3E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 9 | 3Z | bidirectional | Independent output/input terminal of analog switch 3. Paired with 3Y through the bilateral switch; conducts when 3E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 10 | 4Z | bidirectional | Independent output/input terminal of analog switch 4. Paired with 4Y through the bilateral switch; conducts when 4E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 11 | 4Y | bidirectional | Independent input/output terminal of analog switch 4. Paired with 4Z through the bilateral switch; conducts when 4E is HIGH. Signal range 0 V to VCC, switch current up to ±32 mA. |+| 12 | 4E | input | Active-HIGH enable input for switch 4. LOW turns switch 4 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant). |+| 13 | 1E | input | Active-HIGH enable input for switch 1. LOW turns switch 1 OFF; HIGH turns it ON. Schmitt-trigger input; tolerates 0 V to 5.5 V regardless of VCC (5 V tolerant). |+| 14 | VCC | power_in | Supply voltage input. Operating range 1.65 V to 5.5 V; absolute max 6.5 V.
