In this application, one 2-input open-drain NAND gate is used as shown in Figure 8-1. The other three gates 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 inputs are both high, and off any other time.
