Frequently asked questions

How can I make a NOT gate from this IC?

Tie both inputs of one NAND gate together. The output then inverts the single input signal.

What should I do with unused inputs?

Connect unused inputs to VCC or GND. Floating inputs on CMOS logic can cause erratic outputs and higher current consumption.
