3 Applications Information

This section provides general usage information for the design and implementation of the 73S8009CN.

The documents listed in Related Documentation provide more detailed information.

3.1 Example 73S8009CN Schematics

Figure 3 shows a typical application schematic for the implementation of the 73S8009CN with a main

system switch. Figure 4 shows a typical application schematic for the implementation of the 73S8009CN

without a main system switch. Note that minor changes may occur to the reference material from time to

time and the reader is encouraged to contact Teridian for the latest information.
