|---|---|---|---|
| 1 | 1G | input | Active-low strobe (enable) input for section 1; a high level forces output 1Y low. |
| 2 | B | input | Select input B (MSB), common to both sections; unused inputs must be held at VCC or GND. |
| 3 | 1C3 | input | Data input 3 of section 1, selected when B and A are both high. |
| 4 | 1C2 | input | Data input 2 of section 1, selected when B is high and A is low. |
| 5 | 1C1 | input | Data input 1 of section 1, selected when B is low and A is high. |
| 6 | 1C0 | input | Data input 0 of section 1, selected when B and A are both low. |
| 7 | 1Y | output | Data output of section 1, driving ±6 mA at 5 V. |
| 8 | GND | power_in | Ground. |
| 9 | 2Y | output | Data output of section 2, driving ±6 mA at 5 V. |
| 10 | 2C0 | input | Data input 0 of section 2, selected when B and A are both low. |
| 11 | 2C1 | input | Data input 1 of section 2, selected when B is low and A is high. |
| 12 | 2C2 | input | Data input 2 of section 2, selected when B is high and A is low. |
| 13 | 2C3 | input | Data input 3 of section 2, selected when B and A are both high. |
| 14 | A | input | Select input A (LSB), common to both sections; unused inputs must be held at VCC or GND. |
| 15 | 2G | input | Active-low strobe (enable) input for section 2; a high level forces output 2Y low. |
| 16 | VCC | power_in | Supply voltage, 2 V to 6 V, with a 0.1-μF bypass capacitor recommended close to the pin. |
