Unused input pins should be fixed high or low. Generally, the input pins of CMOS products are
high-impedance. Leaving unused pins open can cause the generation of intermediate levels due to
peripheral noise induction. This can result in shoot-through current inside the device and cause it
to malfunction. Table 10.7 lists examples of ways to handle unused pins. Pins marked NC should
be left open.
