13.1 Cascaded operation
In large display configurations, up to 16 PCF8576Cs can be recognized on the same

Table 21.
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
Figure
The PCF8576C can also be cascaded with the PCF8566. The connections are identical to
the PCF8576C cascade.
