Product data sheet
13.1 Cascaded operation
Large display configurations of up to 16 PCF8534As can be recognized on the same
I
I
Table 18.
If cascaded PCF8534As are synchronized, they can share the backplane signals from
one of the devices in the cascade. This is cost-effective in large LCD applications because
the backplane outputs of only one device need to be through-plated to the backplane
electrodes of the display. The other PCF8534As in the cascade contribute additional
segment outputs but their backplane outputs are left open-circuit (see
