Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | XA | bidirectional | Analog input/output terminal of switch A. Bilateral analog path to YA (pin 2) with typical Ron ~70 Ω at VCC=4.5 V. Signal range GND ≤ Vis ≤ VCC. |
| 2 | YA | bidirectional | Analog input/output terminal of switch A. Bilateral analog path to XA (pin 1); enabled when A ON/OFF CONTROL (pin 13) = H. |
| 3 | YB | bidirectional | Analog input/output terminal of switch B. Bilateral analog path to XB (pin 4); enabled when B ON/OFF CONTROL (pin 5) = H. |
| 4 | XB | bidirectional | Analog input/output terminal of switch B. Bilateral analog path to YB (pin 3) with typical Ron ~70 Ω at VCC=4.5 V. |
| 5 | B ON/OFF CONTROL | input | Digital ON/OFF control for switch B. H = switch ON (XB↔YB conducting), L = switch OFF. VIH ≥ 3.15 V and VIL ≤ 1.35 V at VCC=4.5 V. Unused inputs must be tied to VCC or GND. |
| 6 | C ON/OFF CONTROL | input | Digital ON/OFF control for switch C. H = switch ON (XC↔YC conducting), L = switch OFF. CMOS/LSTTL-compatible logic levels referenced to GND. |
| 7 | GND | power_in | Ground / negative supply reference (0 V). Defines the lower bound of the analog signal range (GND ≤ Vis ≤ VCC). |
| 8 | XC | bidirectional | Analog input/output terminal of switch C. Bilateral analog path to YC (pin 9); enabled when C ON/OFF CONTROL (pin 6) = H. |
| 9 | YC | bidirectional | Analog input/output terminal of switch C. Bilateral analog path to XC (pin 8) with typical Ron ~70 Ω at VCC=4.5 V. |
| 10 | YD | bidirectional | Analog input/output terminal of switch D. Bilateral analog path to XD (pin 11); enabled when D ON/OFF CONTROL (pin 12) = H. |
| 11 | XD | bidirectional | Analog input/output terminal of switch D. Bilateral analog path to YD (pin 10) with typical Ron ~70 Ω at VCC=4.5 V. |
| 12 | D ON/OFF CONTROL | input | Digital ON/OFF control for switch D. H = switch ON (XD↔YD conducting), L = switch OFF. Input leakage ±0.1 µA typical at VCC=12 V. |
| 13 | A ON/OFF CONTROL | input | Digital ON/OFF control for switch A. H = switch ON (XA↔YA conducting), L = switch OFF. CMOS/LSTTL-compatible logic levels referenced to GND. |
| 14 | VCC | power_in | Positive DC supply, 2.0 V to 12.0 V (absolute max 14.0 V). Sets the upper bound of the analog signal range and the H-level threshold of the ON/OFF control inputs. |
