Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ON | input | Output-enable input: when low the A and B ports are connected, when high the switch is OFF with a high-impedance state between A and B; control inputs accept TTL or 5-V/3.3-V CMOS levels with VIH up to 5.5 V. |
| 2 | A1 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 3 | A2 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 4 | A3 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 5 | A4 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 6 | A5 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 7 | A6 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 8 | A7 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 9 | A8 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 10 | A9 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 11 | A10 | bidirectional | A-port switch terminal with undershoot protection that keeps the switch OFF for undershoot down to −2 V; data I/O range is 0 to 5.5 V. |
| 12 | GND | power_in | Ground reference for the device; all voltages are referenced to ground. |
| 13 | BIASV | power_in | Bias supply that precharges the B ports; it is a supply voltage (0 to VCC), not a control input. |
| 14 | B10 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 15 | B9 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 16 | B8 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 17 | B7 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 18 | B6 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 19 | B5 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 20 | B4 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 21 | B3 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 22 | B2 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 23 | B1 | bidirectional | B-port switch terminal precharged to BIASV through about 10 kΩ when ON is high or the device is unpowered; data I/O range is 0 to 5.5 V. |
| 24 | VCC | power_in | Supply voltage, specified for 4 V to 5.5 V operation. |
