Product data sheet
12.1 Cascaded operation
Large display configurations of up to 16 PCF85176 can be recognized on the same

I
Table 18.
When cascaded PCF85176 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 PCF85176 of the cascade contribute
additional segment outputs, but their backplane outputs are left open-circuit
