Pin layout is an important factor in determining whether the LSI will operate correctly. The
following shows an example of pin arrangement (Figure 8-10) that takes into account all that
has been explained in this chapter. Refer to this example in determining the pin arrangement
of your application.
Input pins are placed on the upper and left sides of the package, while output pins that change
state simultaneously are placed on the right side. Bidirectional pins and other output pins are
placed on the lower side.
