Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XA | bidirectional | Analog input/output of switch A. Bidirectional analog signal terminal; passes V_CC-to-GND range signals when A control is high. R_ON typ. 70 Ω at V_CC=4.5 V. |
| 2 | YA | bidirectional | Analog input/output of switch A. Bidirectional analog signal terminal paired with XA. |
| 3 | YB | bidirectional | Analog input/output of switch B. Bidirectional analog signal terminal paired with XB. |
| 4 | XB | bidirectional | Analog input/output of switch B. Bidirectional analog signal terminal paired with YB. |
| 5 | B_CTRL | input | B ON/OFF control input. Digital control: H = switch B ON, L = switch B OFF. V_IH ≥ 3.15 V at V_CC=4.5 V; V_IL ≤ 1.35 V. |
| 6 | C_CTRL | input | C ON/OFF control input. Digital control: H = switch C ON, L = switch C OFF. |
| 7 | GND | power_in | Ground / negative supply reference (0 V). Analog signals must remain between GND and V_CC. |
| 8 | XC | bidirectional | Analog input/output of switch C. Bidirectional analog signal terminal paired with YC. |
| 9 | YC | bidirectional | Analog input/output of switch C. Bidirectional analog signal terminal paired with XC. |
| 10 | YD | bidirectional | Analog input/output of switch D. Bidirectional analog signal terminal paired with XD. |
| 11 | XD | bidirectional | Analog input/output of switch D. Bidirectional analog signal terminal paired with YD. |
| 12 | D_CTRL | input | D ON/OFF control input. Digital control: H = switch D ON, L = switch D OFF. |
| 13 | A_CTRL | input | A ON/OFF control input. Digital control: H = switch A ON, L = switch A OFF. |
| 14 | VCC | power_in | Positive supply voltage, 2.0 V to 12.0 V (referenced to GND). Absolute maximum 14.0 V. Sets upper rail for analog signals passed by the switches. |
