Why does National Semiconductor call its DS92001 buffer a \stub-hider\?
The DS92001 has edge transitions optimized for multidrop backplanes where the switching frequency is in the 200 MHz range or less. The output edge rate is critical in some systems where long stubs may be present, and utilizing a slow transition allows for longer stub lengths. In addition, the device is packaged in a small 8-pin SOIC package that can be placed very close to the main transmission line. This reduced stub length dramatically improves the performance of the backplane.
