Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S0B | bidirectional | Multiplexer B source pin 0 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 2 | S2B | bidirectional | Multiplexer B source pin 2 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 3 | DB | bidirectional | Multiplexer B common drain pin for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 4 | S3B | bidirectional | Multiplexer B source pin 3 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 5 | S1B | bidirectional | Multiplexer B source pin 1 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 6 | EN | input | Low-level active logic input that keeps all switches open when high and closes switches per address inputs when low, with 1.8V logic compatible thresholds. |
| 7 | N.C. | unconnected | No internal connection. |
| 8 | GND | power_in | Ground (0V) reference potential. |
| 9 | A1 | input | Address line 1 that controls switch configuration in conjunction with A0 and EN, with 1.8V logic compatible thresholds. |
| 10 | A0 | input | Address line 0 that controls switch configuration in conjunction with A1 and EN, with 1.8V logic compatible thresholds. |
| 11 | S3A | bidirectional | Multiplexer A source pin 3 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 12 | S0A | bidirectional | Multiplexer A source pin 0 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 13 | DA | bidirectional | Multiplexer A common drain pin for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 14 | S1A | bidirectional | Multiplexer A source pin 1 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 15 | S2A | bidirectional | Multiplexer A source pin 2 for bidirectional analog and digital signals supporting input or output operation from GND to VDD. |
| 16 | VDD | power_in | Positive power supply (1.62V to 5.5V); highest potential power pin requiring 0.1µF to 10µF decoupling capacitor between VDD and GND. |
