12.1 Cascaded operation
In large display configurations, up to 16 PCA8576Cs can be recognized on the same

Table 17.
Cascaded PCA8576Cs are synchronized. They can share the backplane signals from one
of the devices in the cascade. Such an arrangement is cost-effective in large LCD
applications since the backplane outputs of only one device need to be through-plated to
the backplane electrodes of the display. The other PCA8576Cs of the cascade contribute
additional segment outputs but their backplane outputs are left open-circuit (see
