Table 17.
Cascaded PCF8576Cs 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 PCF8576Cs of the cascade contribute
additional segment outputs but their backplane outputs are left open-circuit (see
