## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN/OUT by | bidirectional | Analog input/output 'by' of the B switch (channel Y side). Analog signal in the range VEE to VDD; connected to common OUT/IN bx OR by (pin 15) when B=1 and INH=0. |
| 2 | IN/OUT bx | bidirectional | Analog input/output 'bx' of the B switch (channel X side). Analog signal in the range VEE to VDD; connected to common OUT/IN bx OR by (pin 15) when B=0 and INH=0. |
| 3 | IN/OUT cy | bidirectional | Analog input/output 'cy' of the C switch (channel Y side). Analog signal in the range VEE to VDD; connected to common OUT/IN cx OR cy (pin 4) when C=1 and INH=0. |
| 4 | OUT/IN cx OR cy | bidirectional | C-switch common (pole) terminal. Bidirectional analog node connected to either cx (pin 5) or cy (pin 3) as selected by control input C when INH=0. |
| 5 | IN/OUT cx | bidirectional | Analog input/output 'cx' of the C switch (channel X side). Analog signal in the range VEE to VDD; connected to common OUT/IN cx OR cy (pin 4) when C=0 and INH=0. |
| 6 | INH | input | Active-high inhibit input. When INH=1 all three analog switches are turned OFF (channels disconnected). When INH=0 the switches are enabled and controlled by A, B, C. Logic level referenced to VDD/VSS. |
| 7 | VEE | power_in | Analog switch negative supply. Sets the lower limit of the analog signal range (VEE ≤ analog signal ≤ VDD). Typically tied to VSS for single-supply operation; VDD-VEE ≤ 18 V absolute max. |
| 8 | VSS | power_in | Digital ground / logic negative supply. Reference for the control inputs A, B, C and INH. VDD-VSS operating range 3 V to 15 V (18 V absolute max). |
| 9 | C | input | Digital channel-select input for the C switch. C=0 selects cx (pin 5); C=1 selects cy (pin 3). Ignored when INH=1. Logic threshold referenced to VDD/VSS. |
| 10 | B | input | Digital channel-select input for the B switch. B=0 selects bx (pin 2); B=1 selects by (pin 1). Ignored when INH=1. |
| 11 | A | input | Digital channel-select input for the A switch. A=0 selects ax (pin 12); A=1 selects ay (pin 13). Ignored when INH=1. |
| 12 | IN/OUT ax | bidirectional | Analog input/output 'ax' of the A switch (channel X side). Analog signal in the range VEE to VDD; connected to common OUT/IN ax OR ay (pin 14) when A=0 and INH=0. |
| 13 | IN/OUT ay | bidirectional | Analog input/output 'ay' of the A switch (channel Y side). Analog signal in the range VEE to VDD; connected to common OUT/IN ax OR ay (pin 14) when A=1 and INH=0. |
| 14 | OUT/IN ax OR ay | bidirectional | A-switch common (pole) terminal. Bidirectional analog node connected to either ax (pin 12) or ay (pin 13) as selected by control input A when INH=0. |
| 15 | OUT/IN bx OR by | bidirectional | B-switch common (pole) terminal. Bidirectional analog node connected to either bx (pin 2) or by (pin 1) as selected by control input B when INH=0. |
| 16 | VDD | power_in | Positive supply. VDD-VSS operating range 3 V to 15 V (18 V absolute max). Sets the upper limit of both logic and analog signal ranges. |
