| Pin | Symbol | Name/Function |
| 1 2 3 6 7 8 | INA1 INA2 INA3 INB1 INB2 INB3 | TTL-compatible logic input pins for switching channels A and B, respectively (Figure l). A channel switch is normally closed if all of its inputs are logic HIGH. A logic LOW on any input pin will open the switch. |
| 4 | NC | No connection. This pin should not be used as a tie point for external circuitry. |
| 5 | V+ | Connection for most positive external power supply. |
| 9 16 | SWBl+ SWAl+ | One side of the switch output (designated Side l) for channels B and A, respectively. |
| 10 13 | COMMON | Ground or circuit common (not necessarily physical or system ground). All of these pins should be externally connected to one common point. |
| 11 14 | SWB2 * SWA2 * | One side of the switch output (designated Side 2) for channels B and A, respectively. |
| 12 | V- | Connection for most negative external power supply. |
