Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Active-low output enable for switch channel 1; H (≥1.7V at VCC 2.3-2.7V, ≥2V at VCC 2.7-3.6V) disconnects 1A from 1B, L connects 1A to 1B. |
| 2 | 1A | bidirectional | Channel 1 FET switch I/O port A; rail-to-rail bidirectional with 5Ω typical ron at VCC=3V, VI=0, II=64mA; continuous channel current max 128mA. |
| 3 | 1B | bidirectional | Channel 1 FET switch I/O port B; rail-to-rail bidirectional, connected to 1A when 1OE is low; continuous channel current max 128mA. |
| 4 | 2OE | input | Active-low output enable for switch channel 2; H disconnects 2A from 2B, L connects 2A to 2B. |
| 5 | 2A | bidirectional | Channel 2 FET switch I/O port A; rail-to-rail bidirectional with 5Ω typical ron at VCC=3V, VI=0, II=64mA; continuous channel current max 128mA. |
| 6 | 2B | bidirectional | Channel 2 FET switch I/O port B; rail-to-rail bidirectional, connected to 2A when 2OE is low; continuous channel current max 128mA. |
| 7 | GND | power_in | Ground; 0V device reference. |
| 8 | 3B | bidirectional | Channel 3 FET switch I/O port B; rail-to-rail bidirectional, connected to 3A when 3OE is low; continuous channel current max 128mA. |
| 9 | 3A | bidirectional | Channel 3 FET switch I/O port A; rail-to-rail bidirectional with 5Ω typical ron at VCC=3V, VI=0, II=64mA; continuous channel current max 128mA. |
| 10 | 3OE | input | Active-low output enable for switch channel 3; H disconnects 3A from 3B, L connects 3A to 3B. |
| 11 | 4B | bidirectional | Channel 4 FET switch I/O port B; rail-to-rail bidirectional, connected to 4A when 4OE is low; continuous channel current max 128mA. |
| 12 | 4A | bidirectional | Channel 4 FET switch I/O port A; rail-to-rail bidirectional with 5Ω typical ron at VCC=3V, VI=0, II=64mA; continuous channel current max 128mA. |
| 13 | 4OE | input | Active-low output enable for switch channel 4; H disconnects 4A from 4B, L connects 4A to 4B. |
| 14 | VCC | power_in | Power supply; recommended operating range 2.3V to 3.6V, absolute maximum 4.6V; decouple with 0.1µF capacitor placed as close to pin as possible. |
