In this application, one open-drain inverter is used as shown in GUID-9A2FC844-B58E-44D8-8879-F75D30AEB5E0.html#APP1_SCHEM. The other five channels can be used for other applications in the system, or the inputs can be grounded and the channels left unused.
This device is used to directly control an LED. The LED is on when the input is high, and off when the input is low.
