Product data sheet
The contact resistance between the SYNC on each cascaded device must be controlled.
If the resistance is too high, the device is not able to synchronize properly; this is
particularly applicable to chip-on-glass applications. The maximum SYNC contact
resistance allowed for the number of devices in cascade is given in
Table 18.
The PCF8576D can be cascaded with the PCF8562, the PCF8533 or the PCF8534A.
This allows optimal drive selection for a given number of pixels to display.
