Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OE | input | Output Enable 1, active-low control input; high disables Channel 1 multiplexer and forces 1A to high-impedance state |
| 2 | S1 | input | Select Pin 1, CMOS logic input used with S0 to select which of four B ports connects to common A port |
| 3 | 1B4 | bidirectional | Channel 1 I/O 4, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 4 | 1B3 | bidirectional | Channel 1 I/O 3, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 5 | 1B2 | bidirectional | Channel 1 I/O 2, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 6 | 1B1 | bidirectional | Channel 1 I/O 1, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 7 | 1A | bidirectional | Channel 1 common, bidirectional switch port connecting to one of 1B1-1B4 through FET switch when 1OE is low |
| 8 | GND | power_in | Ground, negative supply rail and return path for device current |
| 9 | 2A | bidirectional | Channel 2 common, bidirectional switch port connecting to one of 2B1-2B4 through FET switch when 2OE is low |
| 10 | 2B1 | bidirectional | Channel 2 I/O 1, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 11 | 2B2 | bidirectional | Channel 2 I/O 2, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 12 | 2B3 | bidirectional | Channel 2 I/O 3, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 13 | 2B4 | bidirectional | Channel 2 I/O 4, bidirectional FET switch port with 5Ω typical on-state resistance and rail-to-rail switching capability |
| 14 | S0 | input | Select Pin 0, CMOS logic input used with S1 to select which of four B ports connects to common A port |
| 15 | 2OE | input | Output Enable 2, active-low control input; high disables Channel 2 multiplexer and forces 2A to high-impedance state |
| 16 | VCC | power_in | Supply voltage, operating range 2.3V to 3.6V per Recommended Operating Conditions with maximum continuous current ±128mA |
