Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | S | input | Select input. Chooses which of the two data inputs (I0 or I1) is routed to each Y output when /EN is low. S=L selects I0, S=H selects I1. |
| 2 | IA0 | bidirectional | Channel A data input 0. Bidirectional analog/digital switch pin; connects to YA when S=L and /EN=L. Signal range beyond rail-to-rail (0 to 5 V with 3.3 V VCC). |
| 3 | IA1 | bidirectional | Channel A data input 1. Bidirectional switch pin; connects to YA when S=H and /EN=L. |
| 4 | YA | bidirectional | Channel A common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to IA0 or IA1 via ~5 Ω switch depending on S. |
| 5 | IB0 | bidirectional | Channel B data input 0. Bidirectional switch pin; connects to YB when S=L and /EN=L. |
| 6 | IB1 | bidirectional | Channel B data input 1. Bidirectional switch pin; connects to YB when S=H and /EN=L. |
| 7 | YB | bidirectional | Channel B common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to IB0 or IB1 via ~5 Ω switch depending on S. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | YC | bidirectional | Channel C common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to IC0 or IC1 via ~5 Ω switch depending on S. |
| 10 | IC1 | bidirectional | Channel C data input 1. Bidirectional switch pin; connects to YC when S=H and /EN=L. |
| 11 | IC0 | bidirectional | Channel C data input 0. Bidirectional switch pin; connects to YC when S=L and /EN=L. |
| 12 | YD | bidirectional | Channel D common (mux/demux) pin. Tri-state when /EN=H; otherwise connected to ID0 or ID1 via ~5 Ω switch depending on S. |
| 13 | ID1 | bidirectional | Channel D data input 1. Bidirectional switch pin; connects to YD when S=H and /EN=L. |
| 14 | ID0 | bidirectional | Channel D data input 0. Bidirectional switch pin; connects to YD when S=L and /EN=L. |
| 15 | /EN | input | Active-low enable input. When high, all Y outputs are placed in high-impedance (Hi-Z / disabled) state. When low, the mux passes signals per the S select input. |
| 16 | VCC | power_in | Supply voltage input. Operates at 1.8 V ±10%, 2.5 V ±10%, or 3.3 V ±10%. ICC quiescent current 0.2-0.8 mA typ depending on supply. |
