| 3 | I1 | input | Schmitt trigger input to inverter 1, 5V tolerant (inputs tolerate up to 7V) and must not be left floating. |
| 4 | O1 | output | Inverted output of inverter 1, drives ±24 mA at VCC 3.0V-3.6V. |
| 5 | I2 | input | Schmitt trigger input to inverter 2, 5V tolerant (inputs tolerate up to 7V) and must not be left floating. |
| 6 | O2 | output | Inverted output of inverter 2, drives ±24 mA at VCC 3.0V-3.6V. |
| 7 | GND | power_in | Ground pin. |
| 8 | O3 | output | Inverted output of inverter 3, drives ±24 mA at VCC 3.0V-3.6V. |
| 9 | I3 | input | Schmitt trigger input to inverter 3, 5V tolerant (inputs tolerate up to 7V) and must not be left floating. |
| 10 | O4 | output | Inverted output of inverter 4, drives ±24 mA at VCC 3.0V-3.6V. |
| 11 | I4 | input | Schmitt trigger input to inverter 4, 5V tolerant (inputs tolerate up to 7V) and must not be left floating. |
| 12 | O5 | output | Inverted output of inverter 5, drives ±24 mA at VCC 3.0V-3.6V. |
| 13 | I5 | input | Schmitt trigger input to inverter 5, 5V tolerant (inputs tolerate up to 7V) and must not be left floating. |
| 14 | VCC | power_in | Supply voltage, 2.0V to 3.6V operating (2.3V-3.6V specified), absolute maximum 7.0V. |
